1956 Map of Sulphur Mountain

USGS Topo · Published 1970

About this map

The South Platte River and its Middle Fork dominate this mid-century landscape in South Park, where the valley floor is defined by a complex network of irrigation systems including the Western Grade Ditch, Central Ditch, and Fritz Ditch. These waterways supported established family operations like the Buckley Ranch, Spinney Ranch, and Harrington Ranch, reflecting the era's ranching economy before the downstream reservoirs altered the hydrological character of the basin.
