IN MEMORIAM

Alden Burch Naranjo, Jr.
Southern Ute Indian Tribe
1941–2020

Stories are passed along by grandparents, and each family has a
version of history. History includes personal life experiences of those
elders that shared, and we relate to the past through their stories.

Executive Summary

The Southern Ute Indian Tribe’s Cultural Preservation
Department and NAGPRA Office collaborated with
Anthropological Research, LLC, on Ute ethnographic and
ethno­botanical research in the Bonita Peak Mining District
(BPMD). This work was funded by the Environmental Protection Agency (EPA) through the Environmental Programs
Division as part of the Water Infrastructure Improvements
for the Nation (WIIN) Act. This study will inform the EPA’s
environmental remedial investigations to assess any threats
to Ute people and their culture that were incurred as a result
of the Gold King Mine Spill of 2015 in the BPMD. The spill
produced a high volume of heavy metal contaminants into
the Animas River watershed. At the request of the Southern
Ute Indian Tribe, this research included input from all three
Ute tribes: Southern Ute Indian Tribe, Ute Mountain Ute
Tribe, and the Ute Indian Tribe of the Uintah and Ouray
Reservation, due to their shared concern and historical
connections to the region. Research efforts for this study
included two field trips to the BPMD area, interviews, and
work sessions with Southern Ute and Ute Mountain Ute
tribal members. Due to restrictions and safety concerns
related to the COVID-19 pandemic, meetings and review
sessions were conducted virtually in 2020 and 2021. A total
of 20 Southern Ute and Ute Mountain Ute tribal members
participated in the research. The Ute Indian Tribe contributed to the study through previously documented information and a review of the study findings.
The study primarily focused on Ute plant use and traditional knowledge about the environment. The Southern Ute
Indian Tribe Cultural Preservation Department requested
a comprehensive review of all previously recorded Ute
traditional-­use plant species. Through interviews, fieldwork,

and archival research, 202 traditional-use plant species were
documented with 40 of those plant species observed during
fieldwork. Of these plants, 21 species were recommended
for further toxicological study by the EPA to assess the risk
to Southern Ute tribal members who harvest and use these
plants from the BPMD and the Animas River watershed.
The study also documented other Ute traditional resources
related to the Ute cultural landscape. Trail systems, 55 animal
species, 20 types of water-related resources, 11 minerals, 33
landforms and place names, and 36 Ute terms related to the
sky and constellations were documented. While not the focus
of this study, each of these categories are connected to Ute
plant harvesting practices and traditional use of the BPMD.
Many Ute tribal members continue to visit the BPMD and
the study area on a regular basis to hunt, visit cultural sites,
collect wild plants, and teach tribal youth about Ute culture.
This study also contextualized the aboriginal, historic, and
contemporary developments of the BPMD. Ute traditional
lifeways, historical developments (encroachment, treaties,
and the reservation system, land loss), and perspectives on
traditional land management are summarized in this report.
Ute participants stressed that the impacts from the
Gold King mine spill of 2015 directly relates to the period
of non-Native encroachment that began more than two
centuries prior. Violence, loss of land, environmental degradation, removal from aboriginal areas, and the associated
impacts to health, language, customs, and sovereignty over
their sacred landscape are all part of the lasting legacy of the
mining that occurred in the BPMD. In spite of this, Ute people continue to view the mountainous regions of Colorado
as their sacred landscape. As a Southern Ute-led study, this
project serves as a model for future tribally directed research.

Acknowledgments

This study would not have been possible without the many
Ute tribal elders, past and present, whose words and his­
tories are presented in this report. We would like to extend
a special note of thanks to tribal participants who contributed directly to this project, lending their time, expertise,
and humor while sharing parts of their personal, family, and
tribal histories. As they often remind us, their elders’ words
and deeds continue to guide the present generation, and this
work seeks to preserve that information for generations
to come.
In the course of this study, we were always reminded how
fortunate we are to have had the opportunity to document
some of the Ute history and contemporary Ute connections

to this extraordinary landscape. We have gained a deeper
appreciation for the San Juan Mountains and the Animas
River watershed, and we hope that this report helps all readers better understand how these areas are integral in Ute
history and culture.
The COVID-19 pandemic reminds us of the urgent
nature of our work in historic preservation. The lived
experiences of our elders cannot be replicated, and we are
eternally grateful for the time we have had with those we
have lost. We hope that this work demonstrates the value of
engaging with elders in the places that are most significant
to them, and preserving their stories as they see fit for future
generations.

CHAPTER ONE

Introduction
THE PURPOSE OF this study was to identify culturally
important plants and other resources that may have been
compromised by long-term mining and reclamation in
the Bonita Peak Mining District (BPMD), especially the
resources that may have been impacted by the 2015 Gold
King Mine spill. This study was advocated for by the
Southern Ute Indian Tribe to assess the cultural and health
implications of traditional resources that were affected by
the Bonita Peak Mine Spill in 2015. Although the Environmental Protection Agency (EPA) was already tasked with
completing a remedial investigation that involves collecting data to determine the condition of an affected site, the
nature of the hazard, the risk to human health and the environment, and the treatability of contamination. Due to the
location of the spill within ancestral Ute territory, the area
protected under the Brunot Agreement and its direct impact
on the Animas River watershed, the Southern Ute Indian
Tribe requested the evaluation of potential impacts to cultural resources that continue to be used by tribal members.
In order to address the concerns of the Southern Ute Indian
Tribe, Anthropological Research, LLC (Anthropological
Research) worked with cultural preservation representatives
from the Southern Ute Tribe’s NAGPRA Office to develop
a research strategy to identify research goals. As a result, an
ethnographic and ethnobotanical study was developed for
the BPMD and the surrounding area (Figure 1.1).
The research approach was designed to identify and
document Ute cultural and environmental concerns within
BPMD in order to evaluate potential impacts to Ute lifeways and assist EPA in its remedial investigation of the
area. The assessment of potential impacts to Ute lifeways
was conducted through interviews with tribal elders who
possess familial, tribal, and personal knowledge of the area,
as well as through extensive archival research. Through this

well-rounded approach, information about various topics
was gathered including information about Ute trails; Ute
relations with various groups during the European and
Euro-American occupation, as well as with the US federal
government; and how Ute language, lifeways, and spiritual
cosmology persist and are tied to plants, animals, seasonality, and high-mountain landscapes. In order to document
resources that are connected to but not immediately located
within the BPMD, the study area was expanded to 50 miles
around the BPMD boundary.
The BMPD falls within the traditional ancestral homelands of multiple Ute bands that were separated into separate federally recognized Indian tribes, with reservation
lands in Colorado, Utah, and New Mexico (Figure 1.2). As a
result, all three Ute Indian tribes participated in the research,
including the Southern Ute Indian Tribe, Ute Mountain Ute
Tribe, and the Ute Indian Tribe of the Uintah and Ouray
Reservation (Ute Indian Tribe). Although their ancestors
were forceably removed from the region through deceptive
practices and unfulfilled promises, Ute people retain deep
cultural and historical connections to the San Juan Mountains of Colorado including the BPMD area.
Ute tribal members continue to visit their ancestral lands.
The continued use of the San Juan Mountains and areas
within BPMD plays a critical role in the perpetuation of
traditional knowledge transmission. Tribal members return
on a regular basis to hunt, visit cultural sites, collect wild
plants, and teach tribal youth about Ute culture through oral
histories and cultural teachings.
Tribal members today know and understand the land,
archaeology, history, and natural resources of this region
through traditional cultural knowledge that has been passed
down through generations. This knowledge and understanding is augmented with personal experiences and documented

history about the area. Harm caused to the land and resources
of this region has an inherently adverse cultural effect on
the Ute people. As Betsy Chapoose, Director of the Cultural
Rights and Protection Office of the Ute Indian Tribe put
it, these landscapes are the source of every component of
Ute culture including language, songs, stories, knowledge
of plants, animals, seasons, ceremonies, and lifeways and
the impacts of the spill in this area transcend basic environmental concerns and affect Ute people spiritually and
culturally.

PROJECT BACKGROUND
The area forming the BPMD saw a high concentration of
Anglo-American mining activities spanning the mid-19th
century through the twentieth century. The district encompasses 35 mines, seven tunnels, four tailings impoundments,

and two study areas where additional information is needed
to evaluate environmental concerns. The BPMD encompasses historical and ongoing releases of water from mining
operations in Mineral Creek, Cement Creek, and Upper Animas Creek, all of which flow into the Animas River near Silverton, Colorado. The Gold King Mine is located within the
BPMD near Silverton, Colorado. Remediation activities in
the upper Animas River watershed focusing on reducing the
environmental impacts of inactive mines increased during
the 1990s. On August 5, 2015, the EPA was conducting an
investigation of the Gold King Mine to monitor the release
of water from the mine, treat mine water, and plan further
mine remediation (US Bureau of Reclamation 2015:35–60;
Thayer and Thayer 2018). A project to drain water from
the Gold King Level 7 adit was started but the EPA and its
contractor misjudged the level of water in the mine tunnel.
During the excavation needed to install a drainage pipe,

Introduction  a  3

reservations (after Callaway others 1986; Jefferson and others 1972).

pressurized water in the mine tunnel sprung a leak. This led
to the uncontrolled release of about three million gallons of
contaminated water into Cement Creek, a tributary of the
Animas River. This release temporarily turned the Animas
River a mustard-yellow color for a period of six days (Figure 1.3). The spill received national attention and affected
multiple tribal communities along the Animas and San Juan
watersheds.
News of the 2015 spill and remediation efforts was communicated to community members in part through the Southern Ute Drum (Smith 2016a, 2016b, and 2017; Toledo 2016)
and community meetings held by the Southern Ute Indian
Tribe’s Environmental Programs Division on November 16,
2016. The BPMD became a Superfund site on September 9,
2016 (EPA 2017). In 2017, BPMD was added to the EPA’s

National Priorities List (NPL), requiring the EPA to provide
intense and immediate attention in assessing and mitigating
the short- and long-term effects of the spill. The Southern
Ute Indian Tribe was notified about mitigation funds by the
EPA in 2017. As news circulated among the tribal communities, the Southern Ute NAGPRA Office and Environmental
Protection Department discussed additional opportunities
to evaluate the scope of spill’s impact in regard to cultural
resources within the Brunot Agreement area. Through the
urging of the Southern Ute Indian Tribe, the Environmental Programs Division applied for funding under the Water
Infrastructure Improvements for the Nation (WIIN) act to
document cultural concerns related to the spill.
A central goal of this research was to develop a list of
plants within the BPMD that Ute people harvest, consume,

or interact with so the EPA can determine if heavy metals
and other contaminants associated with mine drainage pose
a health risk to Ute people. Beyond gathering data to assist
the EPA, the Southern Ute NAGPRA Office directed this
study to result in a valuable heritage resource for use by current and future generations of the three Ute tribes and to support future heritage preservation projects. In order to capture
the broad scope of Ute knowledge, history, and traditional
cultural practices associated with the BPMD, a modified
cultural landscape approach was used. This resulted in the
establishment of a 50-mile buffer around the BPMD (see
Figure 1.1).

METHODOLOGY
The research methods used for this project were developed
in collaboration with the Southern Ute NAGPRA Office.
Of particular interest to the Southern Ute Indian Tribe was
the development of a study that included the perspectives
of all three Ute tribes, ethnographic fieldwork and interviews in the study area during all four seasons of the year,
and a comprehensive literature review of previously documented Ute traditional-use resources. Research activities
for this project involved several components, including:
(1) the preparation of a Quality Assurance Project Plan

(QAPP), (2) archival research, (3) ethnographic field visits, interviews, and work sessions with tribal members,
and (4) a report review session with project participants.
Anthropological Research worked closely with the Southern
Ute NAGPRA Office to schedule site visits, select project
participants, and determine when and how to modify project
methods, as needed. Key research personnel included: T. J.
Ferguson, Maren Hopkins, Sean O’Meara, Michael Spears,
and Shawn Kelley from Anthropological Research, William
Widener of GeoSystems Analysis, Cassandra Atencio and
Garrett Briggs of the Southern Ute Cultural Preservation
Department NAGPRA Office, and Terry Knight and Nichol
Shurack of the Ute Mountain Ute Tribal Historic Preservation Office (Table 1.1). Forrest Vaughan and Alexandra
Ratcliff of the Environmental Programs Division of the
Southern Ute Indian Tribe oversaw the project and acted as
liaisons between the research team and the EPA.

Quality Assurance Project Plan
A Quality Assurance Project Plan (QAPP) was required for
this project by the EPA to outline data-collection procedures
and ensure that project requirements were met (EPA 2002).
The QAPP was completed on November 13, 2018, and it
was updated on November 22, 2019.

Archival Research
Extensive archival research was conducted for this project to collect information about Ute history and land use in
the BPMD study area. Anthropological Research reviewed
archival materials at the Southern Ute Cultural Preservation
Department and Southern Ute Museum and Cultural Center
in Ignacio, Colorado; the Ute Mountain Ute Tribe Tribal
Historic Preservation Office in Towaoc, Colorado; the Ute
Indian Museum in Montrose, Colorado; and the San Juan
County Historical Museum in Silverton, Colorado.
Online databases were extensively researched during this
project. These databases include AnthroSource, the Bibliography of Native North Americans, JSTOR, the Native
American Ethnobotany Database, the University of Utah’s
Doris Duke Oral History Collection, and the Rocky Mountain Online Archive (RMOA). Anthropological Research
also used an extensive in-house digital library, which contains resources relevant to Ute culture and history including sources from the Smithsonian’s National Archives and
National Anthropological Archives. Digitized historical
newspapers at the Colorado Historic Newspaper Collection
provided a wealth of information about Ute history in the
BPMD study area. The Ute Indian Tribe also provided digital resources containing ethnobotanical information specific
to the bands associated with their tribe.
Finally, Anthropological Research coordinated with
archaeologists from San Juan National Forest (SJNF) and
the Bureau of Land Management (BLM) Gunnison Field
Office to identify published literature and archival materials
relevant to the current study. Archaeological reports, archaeological site forms, and environmental reports have been
obtained for use in the project.

Ethnographic Fieldwork, Interviews,
and Work Sessions
At the request of the Southern Ute NAGPRA Office, the
original plan of work for this study included fieldwork to the
BPMD during the spring, summer, and fall in order to assess
plants during the three growing and harvest seasons. They
requested that interviews with tribal elders occur during the
winter months, in order to adhere to traditional practices.
Due to heavy snowfall and adverse weather conditions in
the BPMD study area during the spring of 2019, the work
plan had to be modified to include a combination of fieldwork and work sessions at tribal offices.
During the summer and fall of 2019, the research team
visited 10 locations within the BPMD (Table 1.2 and Figure
1.4), as well as other locations within the broader study area.
The goals of the research were to identify Ute traditional-­
plant collection areas and other natural resources to elicit
information about Ute culture, history, and land use in the
study area. Between three and six researchers from Anthropological Research were present for each session. Ethnographic and ethnobotanical information was documented
using handwritten notes, photographs, and digital audio
recorders.
The Southern Ute NAGPRA Office solicited input and
participation from the community through notices in the
Southern Ute Drum, a presentation to the Elder’s Group,
and through follow up calls with people recommended
to participate in the project. Twenty members from the
Southern Ute Indian and Ute Mountain Ute tribes participated in the research for this project (Figure 1.5; Figure 1.6;
Table 1.3). All tribal research participants signed informed
consent forms at the beginning of each research session to

document their understanding of project goals and their
willingness to participate in the research. Study updates
were also provided to the community in 2019 (Southern
Ute Drum 2019).
The study team attempted to involve members of the
Ute Indian Tribe; however, due to scheduling conflicts they
were unable to participate in fieldwork. Plans for Anthropological Research staff to travel to Fort Duchesne, Utah,
to conduct interviews with tribal members were disrupted
by the COVID-19 pandemic, and travel and work restrictions precluded that research from happening. Ute Indian
Tribe perspectives were researched in depth in the literature
review and they are included in this report. The Ute Indian
Tribe Director of the Cultural Rights and Protection Office
met virtually with Anthropological Research staff on September 30, 2020, to provide preliminary feedback.

Winter Work Session
From March 12 to 15, 2019, Anthropological Research
conducted a work session with the Southern Ute and Ute
Mountain Ute tribal members (Figure 1.5). The work took
place at tribal offices in Ignacio and Towaoc, Colorado,
respectively, and included interviews, mapping activities,
plant identification activities, and archival research. Twelve
people from the Southern Ute Indian and Ute Mountain Ute
tribes took place in the interviews and activities. In addition,
Anthropological Research and the Southern Ute Cultural
Preservation Department presented information about the
project to the Southern Ute Indian Tribe Elder’s Group at
their monthly Sip, Chat, and Chew meeting on March 15,
2019, which was attended by 33 people.
Summer Field Session
From August 19 to 21, 2019, the research team conducted
fieldwork in the BPMD study area with four Southern Ute
tribal members and four Ute Mountain Ute tribal members
(Table 1.3; Figure 1.6). Research stops included a visit to

an overlook of the Gold King Mine, Cement Creek, Molas
Lake, and Maggie’s Gulch (Figure 1.4, Table 1.2) Elizabeth Francisco, the BLM archaeologist from the Gunnison
Field Office, accompanied the group on August 20, 2019,
to Molas Lake and Maggie’s Gulch to discuss Ute archaeological sites identified in those areas. On August 21, 2019,
the group visited the Ute Indian Museum in Montrose,
Colorado, where they had a lengthy discussion about Ute
history and plant use that included a tour of the museum’s
ethnobotanical garden.
Fall Field Session
From October 15 to 17, 2019, the research team conducted
fieldwork in the BPMD study area with three Southern Ute
tribal members and five Ute Mountain Ute tribal members
(Table 1.3; Figure 1.4). Elizabeth Francisco, the BLM
archaeologist from the Gunnison Field Office, accompanied the group on October 15, 2019, to Gladstone and the
Velocity Basin to discuss Ute history and archaeological
sites in that area. On October 16, 2019, the group rode the

REPORT OVERVIEW
This report contains seven chapters. Following this introductory chapter, Chapter 2 provides an overview of the Bonita
Peak environmental setting. Chapter 2 orient the reader to
the geology, plants, and water resources of the BMPD study
area, and situate human land use of the San Juan Mountains
within an ecological context. Chapter 3 reviews Ute history
and culture across a broad scale of time and space, including specific connections to the BMPD study area up to the
present day. Chapter 4 describes the Ute cultural landscape
and how Ute cosmology and traditional lifeways are related
to the traditional use of the natural environment. Chapter 5
inventories the plants in the BMPD that are traditionally
used by the Ute people including summaries of ethnographic information identified for each plant species. Chapter 6 summarizes other significant traditional-use resources
identified during the project by Ute research participants.
Finally, Chapter 7 reviews Ute attitudes about the Gold King
Mine spill and the remedial investigation and offers recommendations for the EPA to consider going forward.

During the study, 202 plant species used by Ute people
were identified. Although 162 plant species were identified
only through legacy data and interviews, 40 species were
observed during fieldwork. Many of these plants are used
for more than one purpose. The diversity of uses is shown in
Table 1.4. Additional plants were identified that require further research to determine their significance to Ute people.
Since the project was developed around a holistic approach,
other resources considered culturally important were also
recorded, such as animals, minerals, water resources, and
landforms.
Ute terms are referenced throughout this report. While
attempts have been made to standardize Ute orthography,
differences in dialect and spelling remain. The Southern
Ute Indian Tribe presently uses the linguistic research of
Thomas Givón (2011, 2013a, and 2013b) as the official
orthography of the tribe, but this work does not reflect the
linguistic variation among the three Ute tribes. When the
tribal origin of a Ute term is known, the Ute term is accompanied by a superscript with the following abbreviations:
Southern Ute Indian Tribe= (S), Ute Indian Tribe= (N), and Ute
Mountain Ute Tribe= (M). Ute terms originating from two
bands of the Ute Indian Tribe are abbreviated here as White
River Band= (W) and Uncompahgre Band= (U). Ute language
terms used in this report thus reflect the orthography used at
the time in which the information was collected. The terms
documented during the fieldwork for our study were provided by tribal participants.

CHAPTER T WO

Bonita Peak Environmental Setting

UTE PEOPLE HAVE been inextricably tied to the mountainous landscapes of Colorado since the time of their creation.
The San Juan Mountains, a high and rugged mountain range
within the Southern Rocky Mountains, are the largest mountain range by area in the state of Colorado. Tribal representatives noted that the alpine environment and terrain of the
BPMD are characteristic of the places where the Ute Bear
Dance originated and was regularly traversed as part of Ute
seasonal rounds. The high peaks of the San Juan Mountains
also call to mind the mountain tops that Ute people were
placed upon at the time of their creation.
The San Juan Mountains host some of the tallest mountains in the contiguous United States, with 28 peaks above
9,000 feet and 13 peaks above 14,000 feet. The mountain
range is home to a diverse set of plant and animal communities that vary by elevation and other environmental factors.
The Rio Grande and tributaries of the San Juan, Animas,
Dolores, and Gunnison rivers have their headwaters in the
mountain range, providing water for vast areas of the southwestern United States and northern Mexico.
The geologic events that formed the San Juan Mountains
over tens of millions of years created a distinct set of geological properties that include substantial mineral deposits.
The discovery of these mineral deposits by Euro-Americans
created a rush of development and mining in the late nineteenth and early twentieth centuries. The mining industry
has largely gone dormant, and the San Juans have become
a significant tourism destination, known for alpine beauty,
historic sites, and a variety of outdoor recreation opportunities. Today, much of the region is under the jurisdiction of
the US Forest Service and the Bureau of Land Management,
with small mountain towns dotting the alpine valleys. Farming, ranching, and timber operations also continue.

GEOLOGICAL HISTORY OF THE
SAN JUAN MOUNTAINS
Geologist refer to the period of mountain building in western North America as the Laramide orogeny, which occurred
from 70 to 50 million years ago. The process is described as
a “compressional tectonic event that resulted in thrust faulting, crustal thickening, and mountain uplift across portions
of western North America” (Blair and Gillam 2011:62).
This geologic event caused the broad coastal plain that
covered southwest Colorado to give way to the San Juan
Uplift, which is centered southeast of Silverton, and created adjacent troughs to the south, including the San Juan
Basin. An erosional cycle that followed the San Juan Uplift
removed sediment, exposing the new rock formations, and
transforming the region into an environment that geologists
think consisted of rolling hills and deeply incised valleys
(Blair and Gillam 2011:62–63).
Beginning 35 million years ago, magma pierced the crust
of the earth northeast of the San Juan Mountains, near the
modern town of Saguache. Volcanic centers began to form,
and volcanic activity slowly occurred to the south and west,
in what is today the San Juan Mountains. These eruptions
developed over 20 andesitic composite volcanoes, creating the San Juan Volcanic Field. These volcanos deposited
large amounts of andesitic rocks across the region, creating
a landscape that would have looked similar to the modern
Cascade Mountains in the northwest United States (Blair
and Gillam 2011:63).
Around 30 million years ago, the volcanic eruptions
began to create large calderas that often were tens of kilometers in diameter. The eruptions in this phase of volcanic activity ejected materials that blanketed thousands of

[ 10 ]

Bonita Peak Environmental Setting   a  11

square kilometers, creating a widespread volcanic plateau.
The region would have had rolling topography with scatter
caldera depressions (Blair and Gillam 2011:63–64).
Approximately 25 million years ago, the volcanic field
within the San Juan Mountains region was subjected to an
alternating pattern of erosion and lava flows. This period
also saw the initial development of the Rio Grande Rift east
of the San Juan Mountains. The lava flows largely ceased
by 15 million years ago, and the area was characterized by
moderate erosion for the next 10 million years. Between
5 million and 2.6 million years ago, uplift and block faulting
accelerated (Blair and Gillam 2011:64–66).
The abundant ore deposits in the western San Juan
Mountains contain gold, lead, copper, and zinc. These minerals were deposited near the surface during the doming
and collapse of large volcanic calderas including the Silverton and Lake City calderas. The doming and collapse
was accompanied by faulting insedimentary rocks,which
allowed the slow upward migration of mineral-laden waters
that contained precious metals leached from surrounding
rocks. Near the earth’s surface, cooler temperatures and
lower pressures caused minerals within the solution to separate and move into veins along the side of the faults, where
they then altered the surrounding host rock. Subsequent ore
deposition bound the veins together with the surrounding
rock, and further faulting of the bedrock often shattered the
veins. As a result, the ore veins are heterogeneous, often
following fault lines. They vary based on the surrounding
host rock (Fetchenier 1996:80–81).
Beginning around 5 million years ago, the earth began to
cool, initiating the repeated glaciation of the San Juan Mountains that began 800,000 years ago. At the height of the last
glacial expansion, which occurred 22,000 to 20,000 years
ago, the San Juan Mountains contained a vast ice field that
stretched for 1,900 square miles (5,000 square kilo­meters)
with intermittent exposed mountaintops. This period of glaciation developed the prominent mountain peaks and cirque
basins that are prominent features of the modern San Juans.
The western San Juan Mountains experienced significant
glacial erosion “as gravity pulled massive tongues of ice
down existing river valleys, glacial loads of pulverized rock
ground down bedrock and over-deepened valleys to form
U-shaped canyons” (Blair and Gillam 2011:68). In general,
glacial retreat began around 20,000 years ago and continued
for as much as 10,000 years. Evidence from the Animas
Valley Glacier, however, indicates that glacial retreat began
there around 19,400 years ago and ended 12,300 years ago,
when the ice field disappeared (Blair and Gillam 2011:72).
Over the last 12,000 years, the San Juan Mountains have
continued to evolve geomorphologically in the form of the

movement of rock glaciers (slow moving glacial remnants
buried under their own debris), landslides, and erosion associated with the fire regime (Blair and Gillam 2011:74).
Since the forced removal of the Utes nearly 150 years
ago, major impacts to the mountain range have occurred
that have drastically altered parts of the landscape. Blair and
Gillam (2011:74) write that:
The impact of human activity, both directly and indirectly, on the San Juan landscape is inescapable,
although systematic documentation is lacking. In the
last 150 years, the invasion of gold seekers, farmers
and ranchers, developers, recreational enthusiasts, and
second-home owners have created roads, towns, dams,
mines, and mine waste. (More than 1,500 mine workings have been documented in San Juan County.) Mining activity in the late 1800s and early 1900s accounted
for surges of sediment at 50 to 4,7000 times pre-mining
rates in some places. … In the Upper Animas Valley,
between Howardsville and the old town of Eureka,
sediment surges have increased channel braiding and
added heavy metals to floodplain deposits.

VEGETATION OF THE SAN JUAN MOUNTAINS
The San Juan Mountains encompass a range of vegetative
communities that can be described in a variety of ways.
Floyd-Hanna and others (1996), Jamieson and others (1996),
and Minckley and Brown (1994b) categorize the communities by elevation and keynote species type. Through analysis
of satellite imagery, the LANDFIRE Program, co-managed
by the US Forest Service and the Department of Interior, has
identified 62 vegetation types in the Animas River watershed. Ute tribal representatives have stated that a wholistic view of plant communities that considers Ute cultural
beliefs and practices is useful when considering land habitats. Figure 2.1 illustrates plant commun­ities within the
Animas River Watershed, derived from the LANDFIRE
Program geospatial data and refined using a wholistic view
of the landscape.
The lowest elevations are represented in Figure 2.1 as
intermountain and semi-desert areas. These are dry areas and
south-facing lower elevation slopes where Ute traditional-­
use plants such as prickly pear (Opuntia spp.), Indian ricegrass (Achnatherum hymenoides), sages (Artemisia spp.),
paintbrush (Castilleja spp.), mountain mahogany (Cercocarpus montanus), junipers (Juniperus spp.), currants (Ribes
spp.), and yucca (Yucca spp.) are usually found. FloydHanna and others (1996:144–145) describe these areas
in part as greasewood-shadscale shrub-steppe and Great

12  a  Chapter Two

Basin sagebrush shrub-steppe. The greasewood-shadscale
shrub-steppe community inhabits low-elevation valleys in
poorly drained saline soils that are dominated by greasewood (Sarcobatus vermiculatus) and shadscale (Atriplex
confertifolia). The Great Basin sagebrush shrub-steppe is
present in low-lying well-drained soils and is dominated
by big sagebrush (Artemisia tridentata), blue gramma grass
(Bouteloua gracilis), galleta grass (Pleuraphis jamesii), and
a variety of forbs.
Riparian areas are representative of the key vegetation
community for this study and are hosts to a wide range of Ute
traditional-use plants. These include chokecherry (Prunus
virginiana), narrowleaf cottonwood (Populus angustifolia),
cattail (Typha spp.), mint (Mentha arvensis), horsetails
(Equisetum spp.), wild rose (Rosa spp.), and other waterloving plants. Minckley and Brown (1994b:240) describe
these areas as montane riparian communities along perennial streams between 4,000 and 7,000 feet. They note that
these are often covered in “canyon bottom forest,” which
is generally composed of narrowleaf cottonwood, bigtooth
maple (Acer grandidentatum), box elder (Acer negundo),
alder (Alnus oblongifolia), and willows (Salix spp.). A variety of shrubs also make up an important aspect of montane
streamsides, which also contain trees, shrubs, and grasses
from adjacent montane vegetation communities. According
to Minckley and Brown (1994a:237), subalpine perennial
streams and other aquatic areas are often flanked by varieties of shrub willow (Salix spp.), as well as other scrub
including red elderberry (Sambucus racemosa), gooseberry
(Ribes spp.), and raspberry (Rubus spp.). The riparian areas
may have a few trees that have germinated from surrounding vegetation communities.
Because of the homogenous qualities of piñon-juniper
woodlands and savannas, they are included in their own category (Figure 2.1). Pine nuts are an invaluable and treasured
traditional staple food for Utes and these forests are usually
mixed with open clearings of arid native grasses and shrubs
and stands of larger Rocky Mountain juniper (Juniperus
scopulorum). This community also includes Gambel oak
(Quercus gambelii), a significant traditional-use plant.
Floyd-Hanna and others (1996:146–148) describe these
communities as dominant within the southwestern United
States between 5,000 and 7,750 feet, including the foothills
of the San Juan Mountains. In the lower portion of this zone,
piñon (Pinus edulis) shares canopy dominance with the Utah
juniper (Juniperus osteosperma), while at higher elevations
the Utah juniper is replaced by the Rocky Mountain juniper
(Juniperus scopulorum). Juniper trees have expanded into
adjacent grasslands over the last century due to overgrazing,
droughts, and fire suppression.

Two forest communities are represented in Figure 2.1:
aspen forests and mixed montane forests and woodlands.
Because a single plant can create a large stand of trees,
quaking aspen (Populous tremuloides) communities are
often homogenous, with a mixed understory of wildflowers,
ferns (bracken), and grasses, as well as some Ute traditional-­
use foods such as raspberries (Rubus ideaus) and thimble
berries (Rubus parviflorus). Most notable is the presence
of oshá (Ligusticum porteri), which can be found growing
under aspens at forest edges.
Floyd-Hanna and others (1996:149–153) classify these
edge areas, which occur between 6,000 and 9,500 feet, as
a mixed mountain shrub community, consisting of woody
plants generally under 16 feet in height. There are close
to 50 species within this community,which is a mixture of
species from adjacent communities. Most mixed mountane­
shrub communities are found on steep or moderate slopes.
Biologists consider the mixed mountain shrub community
to represent a stage of recovery in areas that have been disturbed by fire or other disruptions, destined for replacement
by woodland or forest communities given enough undisturbed time.
Mixed montane forests and woodlands refers to communities where Douglas fir (Pseudotsuga menziesii), ponderosa pine (Pinus ponderosa), and other conifers are found.
These are the placeswhere Utes peeled ponderosa pine and
accessed a large array of traditional-use plants. Floyd-Hanna
and others (1996:154) defined these middle elevation zones
as areas between the semiarid foothills and the moist forests
of the high mountains. They note that ponderosa pine was
heavily logged in southwestern Colorado during the late
nineteenth and early twentieth centuries. As a result, most
of the ponderosa pine forests present in the San Juan Mountains today date to the early twentieth century. According
to Jamieson and others (1996:160), mixed conifer forests
are also incorporated in this category. Trees in these forests
include ponderosa pine (Pinus ponderosa), southwestern
white pine (Pinus strobiformis), Douglas fir (Pseudotsuga
menziesii), white fir (Abies concolor), corkbark fir (Abies
lasiocarpa var. arizonica), blue spruce (Picea pungens),
and Engelmann spruce (Picea engelmannii). The dominant
species within a given stand of this community depends on
the soils and other environmental factors.
Due to fire suppression since the late 1800s, the structure
of mixed-conifer forests has not fundamentally changed.
The forests are naturally dense and large-scale crown fires
were part of the normal fire pattern. The lack of fires over
the last century, however, has created a more homogeneous
forest that lacks diversity in stand age and structure. This
makes the mixed-conifer forests less resilient to fire and

LANDFIRE Program.

more vulnerable to insect and disease outbreaks (Korb and
Wu 2011:166–167).
The fire regime and, by extension, the health and nature
of ponderosa pine forests have changed significantly over
the last century. In the past, ponderosa pine forests with an
understory of Gambel oak were well adapted to frequent,
light surface fires that occurred in intervals of 3 to 11 years.
Most fires were small and patchy; more large-scale surface
fires happened approximately every dozen years. The largescale surface fires could burn through thousands of acres
but rarely became crown fires because of the open-stand
structure of ponderosa pine forests. The large-scale surface
fires ended in the late nineteenth century when fire exclusion
policies were implemented to protect Euro-American settlement and livestock grazing. (Korb and Wu 2011:157–158).
By 1880, the San Juan Mountains had become chronically overgrazed by sheep and cattle. This killed or stunted
the grasses and forbs that had previously provided fuel for
the surface fires. Compounding this, land managing agencies
adopted a policy of fire suppression in the early twentieth
century. As a result, the previously open stands of ponderosa
pine were infilled with herbaceous cover, trees, and shrubs.
Today, the open stands of ponderosa pine have largely been
replaced with a closed-canopy forest that lacks herbaceous
understories. The understory is dominated by Gambel oak,
which acts as a “ladder fuel” in the dense ponderosa pine
stands, enabling surface fires to spread from the ground into
the crowns of overstory trees. As a result, the low-severity
surface-fire regime of the ponderosa forest is being replaced
by a regime of high-severity crown fires. The high-severity
crown fires that now spread through ponderosa pine forests
can kill 50 to 100 percent of the trees and shrubs (Korb and
Wu 2011:159).
The subalpine forests, woodlands, and meadows occur
between 9,500 and roughly 11,000 feet. These areas support many valued Ute traditional-use plant species that are
stunted due to the extreme elevation and weather conditions.
Jamieson and others (1996:160) note that most of the tree
species in the mixed-conifer community cannot survive
at these elevations. Willows (Salix spp.) and occasional
stands of oshá (Ligusticum porteri) can be found on sunny
slopes where ample water is present. The spruce-fir forest
commu­nity found in subalpine areas is dominated by Engelmann spruce (Picea engelmannii) and corkbark fir (Abies
lasiocarpa var. arizonica). Historically, the spruce-fir forest fire regime consisted of infrequent, high-severity crown
fires. These forests burned infrequently because of their wet
environment; when lightning strike fires started, they rarely
grew to a significant size. Major fires occurred every 200
or more years and would kill nearly all trees within a burn

area, resetting the spruce-fir stands to the beginning of their
growth process. Spruce-fir and cold-weather mixed-conifer
forests still appear to be within their average fire interval of
200 or more years, but fire suppression and climate change
may impact these ecological zones by decreasing landscape
diversity and the ability of plants to fend off insect epidemics (Korb and Wu 2011:167–168).
Alpine grassland and shrublands communities (areas
above 11,000 feet) are host to a variety of stunted alpine
grasslands, tussock, and moss. These areas are too high in
elevation to support the growth of trees, and most plants
within the communities are low herbaceous plants and small
woody shrubs. These communities favor slow-growing, persistent perennial plants that may take several years to establish during the short growing season. The most common
form of these communities is an alpine meadow, which can
grow as a lush carpet of flowers and forbs during the short
summer (Jamieson and others 1996:169, 170, 172).
At the uppermost elevations in the San Juan Mountains
are treeless alpine vegetation communities and are categorized in Figure 2.1 as sparsely vegetated. These areas are
covered in scree; they serve other purposes in Ute culture.

ECOLOGICAL REGIONS OF THE BPMD
As defined by Chapman and others (2006), ecological
regions are determined by multiple factors including the
geology, vegetation, climate, soils, land use, wildlife, and
hydrology of a given geographical area. Ecological regions
are used by land managers and government agencies,
including the EPA, to understand, evaluate, and create management plans that address site-specific variables. The EPA
Level IV Ecoregions Map of Colorado (Chapman and others
2006) shows that the BPMD study area encompasses three
Level IV ecological regions, which are further classified
into 15 sub-ecoregions (Table 2.1; Figure 2.2). The majority
of lands in the project area and the entire BPMD are classified as the Southern Rockies Ecoregion 21. The western
periphery of the study area, as well as the area south and
east of Durango along the Animas River towards Ignacio,
is classified by the EPA as the Colorado Plateaus Ecoregion
20. The far eastern portion of the study area that includes the
Rio Grande and the western extent of the San Luis Valley is
classified by the EPA as the Arizona/New Mexico Plateau
Ecoregion 22.

to be well-connected regionally and has significant depth.
Evidence from springs and streams indicates that the water
table of the aquifer reaches even the highest elevations in the
San Juan Mountains. Estimates have suggested that groundwater discharge into all the major streams in the San Juan
Mountains is approximately 150 billion gallons of water per
year, which is roughly 3.5 years worth of water for the city
of Denver, Colorado, as of the year 2000. The surface and
groundwater discharge from the San Juan Mountains likely
helps to recharge groundwater in the surrounding San Luis,
San Juan, San Miguel, Uncompahgre, and Gunnison basins
(Caine and Wilson 2011:94–95).
There are approximately 630 bodies of water in the San
Juan Mountains. Many of the natural lakes in the San Juan
Mountains are the result of glacial activity that created
depressions or dammed valleys. Some lakes, such as Little
Molas, result from water dissolving limestone bedrock. The
alpine and sub-alpine lakes within the San Juan Mountains
are generally nutrient-poor and contain less biological diversity than lower-elevation bodies of water. Fish were often
not supported in high-elevation bodies of water but many
previously fishless lakes in the San Juan Mountains have
been stocked with trout over the last century. Many bodies of water contain significant amounts of mercury, which
occurs naturally, comes from mining activity, or is deposited
as atmospheric pollution from coal-fired power plants in the
Four Corners. Mercury levels have significantly increased

since the 1960s, indicating that atmospheric deposition from
coal-fired plants is a major source of the element (Nydick
2011:114, 123, 126).
Fens are the dominate type of wetland in the San Juan
Mountains above 9,000 feet (2,700 m). Fens are distinctive
in that they accumulate organic soil (peat) and are thus considered peatlands. Fens are supported by groundwater and
develop soils because they are permanently saturated. The
slow decomposition rate of the oxygen-free soils within the
fens allows for the accumulation of organic materials. Fens
began to form in the San Juan Mountains approximately
12,000 years ago when the mountain glaciers began to melt.
Many fens in the San Juan Mountains are between 6,000 and
10,000 years old with 3 to 8 ft (.9–2.4 m) of soil depth. Soil
in fens accumulates at a rate of approximately 8 inches per
1,000 years (Chimney and Cooper 2011:129–130). In highly
mineralized areas of the San Juan Mountains, fens can have
significant concentrations of iron and other metals and can
leach significant amounts of heavy metals into surface water
(Stanton and others 2007).
The surface water of the San Juan Mountains drains
through numerous high-elevation streams that feed into
several large rivers. Stream flow is most abundant during the
period of snowmelt between April and July, and additional
water is added by rain from July to September. On the
eastern side of the continental divide the surface water
drains into the Rio Grande, which has its headwaters in the

16  a  Chapter Two

mountain range. The Rio Grande then flows through New
Mexico, Texas, and Mexico to enter the Gulf of Mexico.
On the western side of the continental divide, the surface
water drains into tributaries of the Dolores, Gunnison, and
San Juan Rivers. These rivers all flow into the Colorado
River, which weaves its way through Arizona, Nevada, and
California before entering the Gulf of California in Mexico.

UPPER ANIMAS RIVER AND THE
BONITA PEAK MINING DISTRICT
The Animas River is an important tributary of the San Juan
River and remains one of the few undammed waterways in
western Colorado. It originates in Animas Forks northeast of
Silverton at 11,200 ft and flows south to Farmington, New
Mexico, where it drains into the San Juan River. Along its
course, the Animas River travels through high alpine to arid
desert environments and supports a wide variety of riparian
vegetation communities, The river serves as an important
plant and animal habitat, a water source for agriculture and
municipalities, and as a venue for recreational opportunities
(Somers and Floyd-Hanna 1996:181, 187).
The BPMD, at the center of our study area, is within the
upper Animas River watershed. The upper Animas River
watershed includes the portion of the river from its head­
waters down to the town of Silverton. The Animas River
has two major tributaries, Cement Creek and Mineral Creek,
which enter the river in Silverton. This portion of the watershed is composed entirely of alpine and subalpine habitats,
ranging from 9,300 to 13,800 feet in elevation. There are
three principal basins in the upper Animas River watershed:
Cement Creek, Mineral Creek, and the upper Animas. These
basins are generally steep and narrow glacial valleys that
open into wider valleys such as the one where the town of
Silverton is situated. The steep portions of the three basins
have minimal vegetation, with sporadic spruce-fir forest and
riparian vegetation in less steep areas (Von Guerard and
others 2007:25).

Mining in the Upper Animas River Watershed
The upper Animas River watershed around Silverton, particularly along Cement and Mineral Creeks, was a highly
active and productive part of mining of mineralized deposits
in the San Juan Mountains. Ore containing precious metals was mined from faults along the southern edge of the
Silverton Caldera (Fetchenier 1996:83). Production-scale
mining took place over a 120-year period, from AD 1871 to
1991. The mining followed a boom-and-bust pattern, based
on the price of metals. There were hundreds of mines and

prospect pits were opened during that period, with an estimated total of 18.1 million tons of ore produced from those
mines (Jones 2007).
Prospectors began exploring the San Juan Mountains for
valuable minerals in the 1860s, and by 1872 their finds had
created a small mining rush. In 1873, the Brunot Agreement
was signed, which relinquished the San Juan Mountains
from Ute exclusive ownership (discussed further in Chapter 3). Following the Brunot Agreement, Anglo-­Americans
could legally claim, purchase, and sell land within the San
Juan Mountains, spurring development. A recession and
lack of infrastructure limited development in the 1870s,
however, making small prospecting operations more
common than large mines (Ninnemann and Smith 2006:8,
10, 11–13).
Significant mining development occurred in 1882 after
the cost of transporting ore to market was reduced when
a spur of the Denver & Rio Grande Railroad reached Silverton. Short railroad spurs from Silverton to Gladstone,
Red Mountain, and Animas Forks were added, linking
these mineral-rich areas to the town (Ninnemann and Smith
2006:13–16). Ores were shipped by rail to Durango, where
they were processed at the San Juan and New York Smelter
(Jones 2007:55). Although mining during the early period of
development (AD 1871–1889) was done by hand, the large
mines of the period could still produce approximately 100
tons of ore per day.
Technological advances in the late-nineteenth and early
twentieth centuries (AD 1890–1913) allowed mines to significantly increase their output, and large mines were able
to produce 200 tons of ore per day. These advances included
the construction of aerial tramways to transport ore and
supplies to and from remote mine sites, the advent of the
compressed-air powered machine-drills, and the incorporation of electricity into mining practices (Jones 2007:57).
These advances were particularly significant for remote,
high-altitude mines such as the Gold King and Sunnyside on
upper Cement Creek, which both developed tram systems in
the late-nineteenth century (Jones 2007:54, 58). The environmental impacts of mining increased during this period,
particularly with increased milling at remote sites and the
discharge of tailings directly into streams (Jones 2007:54,
57, 58, 61–63).
World War I created an increased demand for metals,
and technological developments further mechanized the
processes of mining and milling. The introduction of a new
froth-floatation milling process allowed for the mechanized
separation of ores. This significantly reduced the cost of
processing. As a result, miners extracted larger amounts
of lower-grade ore. (Jones 2007:65). In the 1910s, the

18  a  Chapter Two

Sunnyside Mine became the most productive mine in the
region, producing more than 600 tons of ore per day. The
optimism of the early twentieth century was followed by a
postwar recession from 1921 to 1922 that altered the character of mining in the San Juan Mountains. Many small and
medium mines closed permanently, including the Gold King
Mine in 1925. Larger mines, including the Sunnyside Mine,
restarted when the national economy recovered but the local
industry was, from that point forward, dominated by a few,
large producers (Jones 2007:66).
Throughout the Great Depression, World War II, and the
Korean War, the Shenandoah-Dives Mine and its associated
Mayflower Mill was the main producer of ore in the San Juan
Mountains. The Shenandoah-Dives Mine ceased production
in 1953 (Jones 2007:70–72). In 1959, the Sunny­side Mine
was reopened and the Gold King Mill level tunnel, later
renamed the American tunnel, was widened and extended
to reach the Sunnyside veins. This provided economical
transportation of ore and drainage for the Sunnyside mine
workings (Jones 2007:75). High-grade gold ore was discovered at the Sunnyside Mine in the 1970s, which allowed it to
remain in operation until 1991, when the high-grade ore was
exhausted and metal prices declined (Jones 2007:74–76).
With the closure of the Sunnyside Mine, ore production in
the San Juan Mountains became dormant.
Impacts from Mining in the
Upper Animas River Watershed
As a result of the mining of highly mineralized deposits
near its headwaters, the Animas River and its watershed
were exposed to a variety of pollutants. Mining activities
extracted significant quantities of ore and left numerous
toxic tailings piles. The ore extraction and tailings contributed significantly to the level of heavy metals in the Animas River. In addition, naturally exposed ore deposits and
iron bogs leached large amounts of heavy metals into the
upper Animas River. Mineral Creek and Cement Creek,
two important tributaries, contribute significant amounts of
sulfuric acid to the Animas River, causing increased heavy
metal volumes and lower pH values than normal. The
negative impact of these tributaries can be seen for miles
downstream, although the downstream tributaries help to
dilute the toxicity of the water (Somers and Floyd-Hanna
1996:182–185).
Remediation activities in the upper Animas River watershed that focus on reducing the environmental impacts of
inactive mines increased in the 1990s and are on-going.
These efforts include the removal of tailings and mine
dumps, the construction of hydrologic controls to prevent surface runoff, and the plugging of adits and portals.

Although studies suggest that 90 percent of metal loads in
surface water come from only 80 of the 5,300 mining sites
in the upper Animas River watershed, remediation efforts
have been slow. As of 2004, only approximately one-quarter
of high priority sites for remediation had been remediated
(Finger and others 2007:1069).
Gold King Mine Spill
The Gold King Mine has been subject to remediation efforts
since 2008, following a slope failure of a waste-rock dump
on Level 7 of the mine. In 2009, the Colorado Division of
Mining and Safety installed a 2-foot-diameter drain pipe
and an observation pipe above the drain in the collapsed
Gold King Mine Level 7 New Adit in order to direct water
seepage from the adit into a concrete flume (US Bureau of
Reclamation 2015:27–35). Following five years of monitoring, the EPA requested that the Colorado Division of Mining
and Safety reopen and stabilize the Level 7 New Adit. This
work commenced on September 11, 2014, but was quickly
stopped as seepage began flowing during soil removal. Temporary measures were conducted to contain the new seepage
(US Bureau of Reclamation 2015:35–39).
In August 2015, excavations were restarted at the Gold
King Mine Level 7 New Adit and the crew observed seepage similar to that observed in 2014. To safely contain the
water within the Level 7 New Adit, the EPA devised a plan
to excavate collapsed fill from the top of the adit opening,
under the assumption that water levels had not risen to the
adit roof. They would then insert a steel pipe at an angle into
the top of the adit opening and insert it into the pool of water,
from which they could safely pump the water from the adit
for treatment (US Bureau of Reclamation 2015:46–50).
The EPA and its contractor began implementing the plan
on August 5, 2015. As an excavator dug into the debris
that was over-top the adit, water began to flow from the
adit. The rate and size of this flow increased rapidly, and it
quickly became a “blowout,” with the uncontrolled release
of yellow, metal-laden water from the adit. The water flowed
into nearby Cement Creek, eventually entering the San Juan
River from the Animas River, and ultimately making its way
to Lake Powell (US Bureau of Reclamation 2015:52–60).
In total, approximately three million gallons of water
from Gold King Mine Level 7 New Adit containing significant levels of cadmium, arsenic, iron, copper, aluminum,
beryllium, and manganese entered Cement Creek. The water
flowed from the Animas River (Figure 2.3) into the San Juan
River. This caused numerous municipalities in Colorado,
New Mexico, Utah, and the Navajo Nation to swiftly take
action to protect their drinking water supplies (Finley and
McGhee 2015; Turkewitz 2015). While metal levels in the

Animas River returned to pre-spill levels by August 11,
2015, the EPA and other groups continue to investigate the
potential long-term impacts of the Gold King Mine spill
(Colorado Water Quality Control Division 2016).
On September 9, 2016, the EPA designated the Gold
King Mine and 47 other mining-related sources of metal-­
laden water in the Upper Animas, Cement Creek, and Mineral Creek drainages as a Superfund site on the National
Priorities List. The Superfund designation, which provides
federal resources for cleanup, had been resisted by local
residents and businesses for years, because they worried that
the designation may hurt business. In 2016, the US Congress authorized appropriations of $4 million per year for
four years (2017–2021) through the passage of the WIIN
Act. This act funds a long-term water quality monitoring
program for the San Juan watershed (EPA 2021). Since
2016, the EPA has been treating the discharged water of the

Gold King Mine at a temporary treatment plant in Gladstone, as well as conducting monitoring programs, smallscale remediation, and a number of studies to better inform
the large-scale remediation efforts to come (EPA 2020; Finley and McGhee 2015).
Monitoring remains ongoing and from 2016 to 2018,
Mountain Studies Institute sampled 18 sub-basins in
the tributary flows around Bonita Peak that contribute to
Cement Creek and the Upper Animas River. It collected
600 samples from 132 seeps and springs and 31 draining
mines. A large variability in water chemistry was observed
across the study area. The study found that draining mines
generally have larger metal loads than seeps and springs.
The samples included a range of metals including aluminum (Al), cadmium (Cd), copper (Cu), iron (Fe), manganese
(Mn), lead (Pb), zinc (Zn), sulfate ion (SO4) (Cowie and
Roberts 2020).
