The Colorado Oil and Gas Conservation Commission (COGCC) secured Severance Tax Funding for a series of scientific studies known collectively as the 3M Project (Mapping, Modeling, and Monitoring). The Colorado Geological Survey (CGS) was asked to provide the basic mapping components in the form of a geological map of the Fruitland Formation coals as well as subsurface well log cross sections from the outcrop to the Colorado-New Mexico border. A 1:16,000 geologic map was produced along the Fruitland Formation and Pictured Cliffs Sandstone outcrop. It shows the surface extent of the various Fruitland coal beds from the north end of the Southern Ute Indian Reservation at Ridges Basin to the Archuleta County line, a distance of approximately 26 miles. The stratigraphic relationship and lateral continuity of these coalbeds is demonstrated, as are areas of major seeps, distressed vegetation, clinker, springs, coal mines, and high soil gas readings., Laura L.

This report documents the geologic investigations conducted by the Colorado Geological Survey in the Purgatoire River watershed of the Raton Basin of Las Animas County, Colorado. The purpose of this geologic investigation was to provide additional information on the stratigraphic and structural relationships of the coal-bearing formations in the Purgatoire River watershed to assist in the protection and management of both the mineral and water resources contained therein., prepared for Colorado Water Conervation Board ; prepared by Colorado Geological Survey, Ralf Topper, Kenneth Scott, and Nicholas Watterson., "May 2011.", Bibliography: pages 27-29., Online resource; title from PDF cover (viewed March 2018)
