This is a polygon coverage containing eleven different attributes of information including net coal thickness and estimated coal tonnages in the Calico and A-sequences in the Kaiparowits Plateau study area. This layer was derived from a "union" process, i.e., intersection and overlay of numerous layers and retaining attributes of each. It is the result of computing the geometric intersection of ten polygon coverages using the Environmental Systems Research Institute, Inc. (ESRI) Arc/Info UNION command, and finally calculating coal tonnage in INFO. Net coal thickness values are from 209 data points and represent all coal beds that are more than 1 foot thick.CARE SHOULD BE TAKEN IN USING THE COAL THICKNESS AND COAL...

This is a coverage that shows areas in the Kaiparowits Plateauwhere geologic conditions in the Calico and A-sequences are morefavorable for current underground mining technology (Hettinger andother, 1996, fig. 22). This coverage contains nine attributes ofinformation. It was compiled by computing the geometricintersection of nine polygon coverages using the ARC/INFO UNIONcommand.This coverage is characterized as being a guide to where the morefavorable coal areas are likely to be for current undergroundmining technology: areas where coal beds in the Calico and A-sequences are greater than 3.5 feet thick, less than 3,000 feetdeep, and inclined by less than 12 degrees. Note: Coal beds lessthan 3.5 feet thick are generally...
