Summary

The clinker theme represents a digital polygon coverage showing areas where clinker is present. Clinker forms from the natural burning of coal beds in outcrop, and consists of baked (melted) and fused rocks that are commonly red or red-brown in color. In this coverage, only clinker formed by the burning of the Knobloch coal bed is represented. Additionally, clinker of the Knobloch coal bed that is present within the Northern Cheyenne Indian Reservation is not shown. This theme was created specifically for the National Coal Resources Assessment in the Northern Rocky Mountains and Great Plains Region.

Purpose

The Nation's coal resources are being assessed by the USGS. This assessment identifies and characterizes the coal beds and coal zones that will provide the bulk of the Nation's coal-derived energy during the next few decades. This assessment is different from previous USGS assessments because digital files and databases are being collected and stored in standardized formats,and being analyzed using a Geographic Information System (GIS).
