From the Author’s Notes:

Geologic mapping of the Ludwig Mountain 7.5-minute quadrangle was undertaken by the CGS as part of the STATEMAP component of the National Cooperative Geologic Mapping Act. The Ludwig Mountain quadrangle was selected as the second quadrangle to be mapped along the northern rim of the San Juan Basin. The Durango area’s rapid population growth, geologic hazards such as methane seepage, and the natural gas resources give this area a top priority.
