*new* OF-17-02 Geologic Map of the Johnstown Quadrangle, Larimer and Weld Counties, Colorado

The purpose of the CGS Open-File Report OF-17-02, Geologic Map of the Johnstown Quadrangle, Larimer and Weld Counties, Colorado is to describe the geology, mineral and ground-water resource potential, and geologic hazards of this 7.5-minute quadrangle located immediately east of the Front Range uplift of Colorado. The geologic map plates were created using field maps, structural measurements, photographs, and field notes generated by the investigators. Includes 2 plates and GIS data in a single zip file. Digital ZIP download. OF-17-02D

This mapping project was funded jointly by the U.S. Geological Survey through the STATEMAP component of the National Cooperative Geologic Mapping Program, which is authorized by the National Geologic Mapping Act of 1997, and also by the CGS using the Colorado Department of Natural Resources Severance Tax Operational Funds. The CGS matching funds come from the severance paid on the production of natural gas, oil, coal, and metals. Geologic maps produced through the STATEMAP program are intended as multi-purpose maps useful for land-use planning, geotechnical engineering, geologic-hazard assessment, mineral-resource development, and ground-water exploration.
