Description:
Abstract:
This report provides a map and detailed descriptions of geologic
formations for a 1,250 square mile region in the Rawlins–Little Snake
River coal field in the eastern part of the Washakie and Great Divide
Basins of south-central Wyoming. Mapping of geologic formations and
coal beds was conducted at a scale of 1:24,000 and compiled at a scale
of 1:100,000. Emphasis was placed on coal-bearing strata of the China
Butte and Overland Members of the Paleocene Fort Union Formation.
Surface stratigraphic sections were measured and described and well logs
were examined to determine the lateral continuity of individual coal
beds; the coal-bed stratigraphy is shown on correlation diagrams. A
structure contour and overburden map constructed on the uppermost coal
bed in the China Butte Member is also provided.
Purpose:
The data set was collected to acquire data on Upper Cretaceous and
Tertiary coal-bearing strata in the eastern Washakie and southeastern
Great Divide Basins. These regions of south-central Wyoming have
potential for coal development and were considered previously for coal
leasing by the U.S. Bureau of Land Management.

Attribute_Accuracy:
Attribute_Accuracy_Report:
The database consists of newly generated data that were compiled
on scale-stable greenlines and then digitized in ARC/INFO. This map
was thoroughly reviewed for conformity with U.S. Geological Survey
editorial standards and stratigraphic nomenclature.
Logical_Consistency_Report:
Map elements were visually checked by the authors, cartographers,
and editor for overshoots, undershoots, duplicate features, polygon
attributes, and other errors. The coverages were cleaned in
ARC/INFO to ensure logical consistency that is topologically clean.
The map was reviewed by other geologists for consistency with basic
geologic principles and general conformity to USGS mapping
standards.
Completeness_Report:
This dataset is complete and includes the spatial coverages
pertaining to the geologic map.

Horizontal_Positional_Accuracy_Report:
Users of this digital geologic map should respect the
intentions of the original mappers and the map compilers, and
the limitations of the map. The geology data set is intended to
be used at a scale of 1:100,000. It is not intended to be used at a
more detailed scale.

Process_Step:
Process_Description:
Most of the geologic mapping was based on field observations, analysis
of black and white aerial photographs (scale 1:28,000 and 1:20,000,
flown in 1975) and color aerial photographs (scale 1:36,000, flown in
1975), and drill-hole data. Some mapping was compiled from previously
published investigations. All sources of data are referenced in
figure 2 of the report. Geologic contacts were selected and
transferred onto 1:24,000-scale topographic base maps. The resulting
maps were reduced in scale and transferred onto the 1:100,000-scale
topographic bases of the Baggs and Rawlins 30 x 60-minute quadrangles.
The resulting line work was digitized using ArcMap 9.1.
The structure contour and overburden map of the uppermost coal bed in
the China Butte Member of the Fort Union Formation was determined from
geophysical well logs and outcrops mapped at a scale of 1:24,000.
Structure elevations and overburden thickness were contoured manually
at a scale of 1:24,000 and transferred onto the 1:100,000-scale
topographic base of the Baggs and Rawlins 30 x 60-minute quadrangles.
The resulting line work was digitized using ArcMap 9.1.
Coal-bed correlations were constructed from stratigraphic sections
measured in the field, interpretations of geophysical logs from
numerous coal test holes, and correlations made from outcrops and
photogeologic mapping.
