OF-13-07 Geologic Map of the Olathe NW Quadrangle, Delta and Montrose Counties, ColoradoE-mail this product to a friend
The purpose of CGS Olathe Northwest Quadrangle Geologic Map, Delta and Montrose Counties, Colorado is to describe the geology, mineral and ground-water resource potential, and geologic hazards of this 7.5-minute quadrangle located southeast of Delta in western Colorado. CGS staff geologists David Noe, Matt Morgan, and field assistant Shannon Townley (now with Cornerstone Natural Resources) completed the field work on this project during the spring and summer of 2007. The geologic map plates and the Authors’ Notes report were created using field maps, field notes, structural measurements, and photographs generated by the investigators. Surficial and bedrock unit descriptions were coordinated between this area and the adjacent Delta and Olathe quadrangles (Morgan and others, 2007; 2008). This mapping project was funded jointly by the U.S. Geological Survey (USGS) and CGS. USGS funding comes from the STATEMAP component of the National Cooperative Geologic Mapping Program, award number 07HQAG0083, authorized by the National Geologic Mapping Act of 1997, reauthorized in 2009. CGS matching funding comes from the Colorado Department of Natural Resources Severance Tax Operational Funds, from severance taxes paid on the production of natural gas, oil, coal, and metals in Colorado.
