1954 Map of Red Hill

USGS Topo · Published 1973

About this map

Trigo Mountains and the Middle Mountains dominate this arid landscape, which in the mid-1950s served as a critical intersection of federal land management and military activity. The expansive Yuma Test Station occupies the central basin, bordered by a Military Reservation that transitions into the rugged Castle Dome Plain. The southwestern corner is marked by the Imperial National Wildlife Refuge along the Colorado River corridor. Economic and cultural history is evidenced by resource extraction and early transit, including the Castle Dome Mine, the Annie Mine, and a primitive Indian Trail. Significant drainage patterns are defined by the Yuma Wash and McAllister Wash, which carve through the high terrain around peaks like Trip Mtn and Red Hill.
