OF-08-16 Geologic Map of the Dakan Mountain Quadrangle, Douglas, Teller and El Paso Counties, Colorado


Describes the geologic setting, mineral and water resources, and geologic hazards of this 7.5-minute quadrangle located in the Front Range, north of Woodland Park, Colorado. Consulting geologists Jay Temple, Alan Busacca, and field assistants David Mendel and Karri Sicard completed the field work on this project during the summer of 2007. The sedimentary bedrock unit descriptions, structural geology, and water resource sections of this report were written by Mr. Temple. Dr Busacca completed the sections on surficial deposits and geologic hazards. Mr. Mendel and Ms Sicard contributed the crystalline bedrock unit descriptions and mineral resources section.

From the Author’s Notes:

The Dakan Mountain 7.5-minute quadrangle is located in Douglas, Teller, and El Paso Counties, Colorado, in the southern part of the Colorado Front Range. The mapped area is predominantly mountainous terrain and a part of the Rampart Range. The city of Colorado Springs (Census 2000 population of 360,890) is located approximately 20 miles southeast of the quadrangle. The town of Woodland Park (Census 2000 population of 6,515) is located 8 miles to the south of the quadrangle. State Highway 67 transects the southwest quarter of the Dakan Mountain quadrangle and connects Woodland Park with the towns of Deckers, Buffalo Creek, and Pine Junction. Rampart Range Road (Forest Service Road 300) runs northwest-southeast through the quadrangle along the drainage divide between streams draining to the east and streams draining to the west. Trout Creek, the major drainage throughout the southwestern part of the Dakan Mountain quadrangle, flows northward to join the South Platte River near the town of Deckers. The South Platte watershed supplies a large share of water consumed by Denver and other cities to the north and east along the foothills of the Front Range. Several creeks and streams that originate in the mountains in the eastern part of the Dakan Mountain quadrangle flow into Trout Creek. The highest point in the mapped area is Storm Peak, located in the extreme east-central part of the quadrangle in sec. 9 of T. 10 S., R. 68 W. (elevation 9,199 feet). The lowest point (elevation 7,440 feet) is in the southwestern part of the quadrangle in the Trout Creek bottom north of Rainbow Falls Park.
