1961 Map of Mount Big Chief

Evidence of historical land use is scattered throughout the drainages of South Cheyenne Creek and Gould Creek, with numerous prospects and a quarry indicating the area's geological value. High peaks like Mount Big Chief and St Peters Dome overlook small settlements such as Rosemont and Duffield, while the southwestern corner shows an indefinite boundary between Teller, El Paso, and Fremont counties, reflecting the complex surveying history of this mountain terrain.
