1972 Map of Rattlesnake Canyon

About this map

San Bernardino National Forest dominates the southern half of this landscape, where the high ridges of the Granite Peaks and Tip Top Mountain overlook the arid expanse of Johnson Valley to the north. Surveyed in the early 1970s, the map reveals a rugged backcountry accessible primarily by a network of jeep trails and footpaths. This era of land use is marked by scattered resource extraction, with numerous Mines and Prospects dotting the slopes, particularly near Rattlesnake Canyon. Water sources are vital landmarks in this high-desert environment, identified by distinctive names such as Two Hole Spring, One Hole Spring, and the clustered Viscera Springs. The presence of a Radio Facility near the southern boundary reflects the modern infrastructure beginning to reach these high elevations during the mid-20th century.
