The purpose of the Eastonville Quadrangle Geologic Map, El Paso County, Colorado is to map and describe the geologic setting, structure, geologic hazards, and mineral and ground-water resources of this 7.5-minute quadrangle located northeast of the Colorado Springs metro area in east-central Colorado. CGS geologists Matthew L. Morgan and Peter E. Barkmann completed the field work on this project during the spring and summer of 2009. Some unit descriptions were coordinated between this area and the neighboring Black Forest (Thorson, 2004b) and Elizabeth (Morgan, 2009) quadrangles. Digital ZIP download. OF-12-03D
From the authors notes:
The Eastonville 7.5-minute quadrangle is located northeast of Falcon, Colorado, in the southern part of the Colorado Piedmont section of the Great Plains. The quadrangle is situated in the Kiowa Creek and Black Squirrel Creek drainage basins, which are tributary to the South Platte River and Arkansas River, respectively. Geologic mapping of the Eastonville 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.
