OF-07-04 Geologic Map of the Ponderosa Park Quadrangle, Douglas and Elbert Counties, Colorado

The purpose of this map is to describe the geologic setting, mineral and ground-water resources, and geologic hazards of this 7.5-minute quadrangle located southeast of Denver in central Colorado. Consulting geologist Jon P. Thorson completed the field work on this project during the summer of 2006. Digital ZIP/PDF download. OF-07-04D

From the Author’s Notes:

The Ponderosa Park 7.5-minute quadrangle is located east of Castle Rock, Colorado, in the southern part of the Colorado Piedmont section of the Great Plains. The quadrangle is located in the Cherry Creek and Coal Creek drainage basins, which are tributary to the South Platte River. Geologic mapping of the Ponderosa Park quadrangle was undertaken by the Colorado Geological Survey (CGS) as part of the STATEMAP component of the National Cooperative Geologic Mapping Program. 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, and ground-water evaluation.
