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.
The goal of this study is to relate coalbed methane occurrence and producibility to geologic and hydrologic settings, leading to models for exploration and production.
