The U.S. Geological Survey conducted an assessment of coal resources and reserves in the Little Snake River coal field and Red Desert area of the Greater Green River Basin in Southwest Wyoming. A comprehensive database was compiled to support this assessment that includes data points for drill-holes and measured sections. Associated with these resources are lithology descriptors, (focusing on coal beds of varying depth) as well as coal quality data. Sources of data includes the USGS National Coal Resources Data System (NCRDS), Anadarko Land Corporation (Anadarko), Wyoming Oil and Gas Conservation Commission (WOGCC), and previously unpublished data in USGS files. The primary table describes the sample location and contains 4,214 data points with 2,593 coal drill holes, 1,101 oil, gas, and coalbed methane (CBM) wells, and 520 measured sections. A second table documents coal lithology and correlated formation & coal bed names. This table has 78,701 stratigraphic records. Coal quality analytical data existed for 299 drill holes for a total of 906 records which reside in the third table. A unique identifier is assigned to each table to link the related records.
