1994 Map of Sulphur Mountain

USGS Topo · Published 1998

About this map

Sulphur Mountain and the high-altitude ranching landscape of Park County are captured here in a 1990s survey, showing the complex water-management systems required for this arid terrain. The South Platte River and its Middle Fork feed into the Spinney Mountain Reservoir, supported by an intricate network of irrigation channels including the Harrington Ditch, Fritts Ditch, and Western Ditch. Residential development is concentrated at Pike-San Isabel Village, while the surrounding land remains largely dedicated to large agricultural holdings such as Buckley Ranch, Spinney Ranch, and Harrington Ranch. The northern reaches include portions of the Pike National Forest and various geological markers like Chalcedony Spring and an isolated Oil Well. Significant land use designations like the Spinney Mountain Wildlife Area highlight the region's shift toward conservation and public recreation at the end of the 20th century.
