These data represent the boundary of the Wyoming Landscape 

Conservation Initiative (WLCI). The WLCI is part of the Healthy Lands 

Initiative. The boundaries used for creating this dataset are as follows:

South: Wyoming-Colorado/Wyoming-Utah State Line

West: Wyoming-Utah/Wyoming-Idaho State Line

North: Lincoln-Teton/Sublette-Teton/Sublette-Fremont County line; 

following the Fremont County Line to the crossing of the Continental 

Divide and Fremont County. In Fremont County: all of the area south of 

the Divide. Where the Divide enters Sweetwater County, the boundary is 

the Fremont-Sweetwater County line. Once the Divide meets the Carbon 

County line, then Carbon County forms the northern boundary. 

East: Carbon-Albany County line

This data set shows mapped and inferred coal outcrops clipped to the WLCI 

from a Wyoming state layer. This data set was compiled from Coal 

Resource and Occurrence Reports, Wyoming State Geological Survey 

publications, and other various reports and theses. Where availiable, this 

data set includes coal bed name, thickness, and basin name (Jones and 

others, 2009). Outcrops are also available in the Rawlins–Little Snake River 

Area for coal beds in the Fort Union Formation and the Nebraska coal bed 

in the Fox Hills Formation (see Rawlins–Little Snake River Area Geology and 

Coal Stratigraphy).

Because this region of south-central Wyoming has potential for coal 

development and was considered previously for coal leasing by the BLM, 

geologic data were mapped and published by the USGS for a 1,250 mi

2 

region in the Rawlins–Little Snake River coal field in the eastern part of the 

Washakie and Great Divide Basins. Emphasis was placed on coal-bearing 

strata of the China Butte Member and the Overland Member (part) of the 

Paleocene Fort Union Formation. A structure contour and overburden 

map constructed on the uppermost coal bed in the China Butte Member is 

included (Hettinger and others, 2008).

These map services are designed to be used by GIS professionals to overlay 

basemaps and thematic maps such as demographics or land cover for 

reference purposes. These services include administrative boundaries, 

cities, water features, physiographic features, parks, landmarks, highways, 

roads, railways, and airports on a transparent background. The services 

were compiled from a variety of the best available data sources, including 

the U.S. Geological Survey (USGS), National Park Service, Tele Atlas, and 

ESRI. The services currently provide coverage for the world down to a scale 

of about 1:1m and coverage for the continental United States and Hawaii 

to a scale of about 1:70k (ESRI, 2009).

If ArcMap is used, these services do not draw correctly unless 9.3.1 or a 

more recent version is used because it is cached using the PNG32 graphic 

format, which is not supported in ArcMap prior to 9.3.1. It can be used in 

ArcGlobe version 9.3 or more recent (ESRI, 2009).

These data show location and status of coalbed natural gas (CBNG) wells, 

authorized and pending CBNG leasing units, and oil and gas pipelines 

clipped to the Atlantic Rim area, Carbon County, Wyoming. The data are 

from the Wyoming State Geological Survey, Atlantic Rim Area Coalbed 

Natural Gas Map, WSGS Open-File Report 09–7 (Quillinan and others, 

2009). Generally, a limiting economic consideration for exploration and 

development of petroleum resources are the locations of pipelines, 

refineries, and gas processing plants (Quillinan and others, 2009).

The Mesaverde Coalbed Gas Assessment Units (AU) are defined as the 

areas where significant coal is present in the Almond Formation (Johnson 

and others, 2005) and in the Rock Springs Formation at depths of 6,000 ft 

or less. Commercial production rarely extends to depths greater than 6,000 

ft (Finn and others, 2005). The Lance Coalbed Gas AU includes areas where 

coals in the basal 300–500 ft of the Lance Formation are interpreted to be 

at depths of 6,000 ft or less (Roberts, 2005). The Fort Union Coalbed Gas 

AU include areas where coals in the Fort Union Formation are interpreted 

to be at depths of 6,000 ft or less (Roberts, 2005; Finn and others, 2005). 

The Wasatch–Green River Coalbed Gas AU includes areas where coals in 

the main body, and Red Desert and Niland Tongues of the Wasatch 

Formation, and the Luman Tongue of the Green River Formation are 

present in outcrops and in the shallow (depth less than 2,500 ft) subsurface 

(Roberts, 2005b). The Frontier-Adaville-Evanston Coalbed Gas AU is in the 

Wyoming Thrust Belt Province (Kirschbaum and others, 2004). The U.S. 

Geological Survey estimated a mean of 1.89 trillion cubic feet (TCF) of 

undiscovered coalbed natural gas in the Southwestern Wyoming 

(Kirschbaum and others, 2002) and Wyoming Thrust Belt (Kirschbaum and 

others, 2004) Provinces.

The National Coal Resources Data System (NCRDS) is a national coal 

database containing stratigraphic records from cores and field 

observations. Data were collected by the U.S. Geological Survey and 

cooperating State geological survey agencies. This dataset represents the 

publicly available stratigraphic data as of 2002 and contains about 50 

parameters describing the point location, data source, and coal 

information such as formation and bed name, thickness, top and bottom 

depths, and lithology. NCRDS data was developed to provide a large, 

comprehensive and publicly available digital coal database to be used in 

the estimation of coal resources in the United States.

A unit agreement is an agreement approved by the authorized officer of 

the Bureau of Land Management (BLM) on behalf of the owners of oil and 

gas interests over a potential oil or gas reservoir who wish to unite to 

facilitate the orderly and timely development of the oil and gas resources 

within the unit area. This consolidation of separate leasehold interests 

eliminates the need to drill protective wells along common boundaries 

between unitized leases and serves to maximize benefits through a 

continuing exploration and development program (U.S. BLM, 2010d). The 

data for the wells are from the Wyoming Oil and Gas Conservation 

Commission (WOGCC) and include those classified as coalbed gas wells 

(WOGCC, 2010).

This data set was clipped to the WLCI from a polygon coverage 

representing the coal fields of the United States. Resolution of data is 

1:5,000,000. Most of the material for the conterminous United States was 

collected from James Trumbull's Coal Fields of the United States (sheet 1, 

1960) map (Tully, 1996).

A wind turbine GIS dataset (O'Donnell and Fancher, 2010) derived from 

aerial photographs available through the National Agriculture Imagery 

Program, provides information about each wind turbine's megawatt 

potential, size and manufacturing details, land ownership, power owners 

and users, and operational status. 

There are three datasets available for electric power generation sites. One 

was published by Jones and others (2009) as part of the Coal Map of 

Wyoming, and those data and annotations are shown on plate 1. The 

others were published in 2010 and include electric power-generating 

facilities over 1 megawatt (Stafford, 2010a) and wind farm projects 

(Stafford, 2010b). Some of the 2010 data are shown on plate 1, for those 

facilities not included in Jones and others (2009). All of the data published 

in the 2010 shapefiles are included in the Energy Map geodatabase. The 

'Consumers' layer contains 3 industrial facilities that are coal users.

The 1999 USGS coal assessment of the Northern Rocky Mountains and 

Great Plains region focused on selected coals in rocks of Tertiary age that 

will provide the bulk of the nation's coal-derived energy during the next 

few decades. Two of the areas are within the WLCI and include the 

Greater Green River Basin and the Hanna-Carbon Basin. Summaries of coal 

resources calculated by basin are 2.7 billion short tons in the Greater 

Green River Basin and 7.2 billion short tons in the Hanna-Carbon Basin. 

Many of the Tertiary coals in the Northern Rocky Mountains and Great 

Plains region contain low amounts of sulfur, ash, and trace elements of 

environmental concern. Because of the low level of these contaminants, 

most Tertiary coal is classified as compliant coal for use in electrical 

generation (USGS Fort Union Coal Assessment Team, 1999).

This geologic map was prepared as part of a study of digital methods and 

techniques as applied to complex geologic maps. The geologic map was 

digitized from the original scribe sheets used to prepare the published 

Geologic Map of Wyoming (Love and Christiansen, 1985), and 

consequently, is at 1:500,000 scale. Each vector and polygon was given 

attributes derived from the original 1985 geologic map. The data are 

intended to be used as a base geologic map, and are accessible online 

(Green and Drouillard, 1994).

These layers are published in the Wyoming State Geological Survey 

(WSGS), Coal Map of Wyoming, WSGS Map Series 93 (Jones and others, 

2009). The origin of the roads data is the 1995 Bureau of Census 

TIGER/Line Files, the railroads data are from the Wyoming Department of 

Revenue (1999) and the electric lines data were developed by the USGS, 

Snake River Field Station in 2004.

For each assessed coal, net thickness categories were compiled and 

published in a geographic information system (GIS). In the Green River 

Basin, coal thickness categories represent the Deadman coal zone. In the 

Hanna Basin, several coal beds were assessed in the Ferris and Hanna 

Formations. In the Carbon Basin, the Johnson-107 coal zone was assessed 

(USGS Fort Union Coal Assessment Team, 1999).

This dataset represents surface and mineral ownership for Wyoming, and is 

intented to represent the ownership information on Master Title Plats 

(MTPs). When the surface is Federal, surface ownership is identified by the 

Agency of Juridiction. All other parcels are identified as either private or 

state. Mineral ownership identifies only the federal interest (U.S. BLM, 

2009b).

The only active underground coal mine is the Jim Bridger longwall 

operation on the east flank of the Rock Springs uplift. The only active 

surface mine in Carbon County is the Elk Mountain/Saddleback Mine 

operated by Arch Coal; it will be converted to an underground mine if a 

coal-to-liquids plant is constructed near Medicine Bow. All other mines in 

the Hanna area are either abandoned underground workings or reclaimed 

surface mines (Jones, 2010, oral commun.). Surface coal mines are active 

on the east flank of the Rock Springs uplift and at the Kemmerer coal mine 

in Lincoln County. Another coal mines layer is included from the University 

of Wyoming Dept. of Geography (WyGISC, 2002). This layer shows mine 

locations and production in 1999, is included in the Energy Map 

geodatabase, but not visible on the PDF map.
