Wallack, Rachel N.

This dataset is the digital compilation of geologic and resource maps provided mostly by State geologic surveys and depicts the projected area of occurrence of the Upper Freeport coal bed. The Upper Freeport coal bed is in Ohio, West Virginia, western Pennsylvania, and western Maryland. The coal bed may extend into eastern Kentucky, but correlations are highly uncertain and do not warrant extrapolation south of the areas shown on this map at this time. This dataset represents the extent of the Upper Freeport coal bed used in the Apalachian coal region assessment. The file has been generalized from detailed geologic coverages found elsewhere in Professional Paper 1625-C.

This dataset is a polygon coverage of counties limited to the extent of the Upper Freeport coal bed resource areas and attributed with statistics on the thickness of the Upper Freeport coal bed, its elevation, and overburden thickness, in feet. The file has been generalized from detailed geologic coverages found elsewhere in Professional Paper 1625-C.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
