| Description |
The purpose of Colorado Geological Survey’s (CGS) Orchard City Quadrangle Geologic Map,Delta County, Colorado is to describe the geology, mineral and ground-water resource potential, and geologic hazards of this 7.5-minute quadrangle located west of Delta in western Colorado. CGS staff geologist David Noe and field assistant Michael Zawaski completed the field work on this project during the summer of 2009. The geologic map plates and the Authors’ Notes report were created using field maps, structural measurements, photographs, and field notes generated by the investigators. 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 G09AC00192, 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.
