Description:
Abstract:
This report provides a geologic map of the Blue Gap 7.5-minute
quadrangle, located along the eastern flank of the Washakie Basin,
Wyo. Geologic formations and individual coal beds were mapped at a
scale of 1:24,000; surface stratigraphic sections were measured and
described; and well logs were examined to determine coal correlations
and thicknesses in the subsurface.
Purpose:
The data set was collected as part of a larger effort to acquire data
on Upper Cretaceous and Tertiary coal-bearing rocks in the eastern
Washakie Basin and southeastern Great Divide Basin. Regions in the
eastern Washakie Basin and southeastern Great Divide Basin 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 a
scale-stable greenline of the Blue Gap quadrangle 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 of the Blue Gap quadrangle is intended
to be used at a scale of 1:24,000. It is not intended to be used at
a more detailed scale.

Process_Step:
Process_Description:
Mapping was based on field observations, analysis of black and white
aerial photographs (scale 1:29,000, flown in 1975), color photographs
(scale 1:36,000, flown in 1975)topographic maps (scale 1:24,000), and
drill-hole data. The linework was transferred from aerial
photographs to base maps using a PG-2 stereo-plotter, and digitized
manually, and the data were then digitally registered to a digital
version of the base map in ARC/INFO. Geologic cross sections show
the subsurface thickness of coal beds in the units of interest. The
cross sections were constructed using stratigraphic sections measured
in the field and from borehole electrical logs.
