This is a shapefile and the final unioned polygon coverage used to calculate coal resources of the Fruitland Formation, San Juan Basin coal assessment area, Colorado and New Mexico. Polygons that make up the final unioned polygons include counties, 7.5' quadrangles, townships, surface and coal ownership, reliability, overburden categories, and net coal thickness categories. The final unioned coverage was clipped by the resource boundary polygon, which is described in the metadata file for the shapefile SJB_BND.

This is a shapefile and coverage of data points used in the assessment of coal resources of the Fruitland Formation in the San Juan Basin, Colorado and New Mexico. Data in this file include a point identifier, x, y, location; surface elevation of the drill hole; elevations for the top of the uppermost coal and for the base of the lowermost coal; net coal thickness of coal beds greater than or equal to 1.2 ft; and number of beds comprising the net coal thickness.
