From the Introduction:
Geologic mapping of the Durango East 7.5-minute quadrangle was undertaken by the Colorado Geological Survey (CGS) as part of the STATEMAP component of the National Cooperative Geologic Mapping Act. Geologic maps produced by the CGS through the STATEMAP program are intended as multi-purpose maps useful for land-use planning, geotechnical engineering, geologic-hazards assessment, mineral resource development, oil and gas development, and ground-water exploration. Mapping in the Durango region also contributes to the understanding of the fracture network through which natural gas may migrate.
