1966 Map of Jensen Ridge

About this map

Diamond Mountain Plateau dominates the northern elevation of this landscape, giving way to a complex system of drainage and relief. To the south, the terrain descends toward The Reef, where the Stone Bridge Draw and South Fork Jensen Wash carve through the geological formations. This mid-1960s survey, conducted in cooperation with the U.S. Bureau of Reclamation, documents a high-desert environment utilized for seasonal water management and grazing. Essential water sources for livestock or early settlers are mapped throughout the draws, including Switchback Spring, Blair Spring, and Coal Bed Spring. Man-made improvements to the landscape are evident in the placement of a prominent Pipeline crossing the western sections and the establishment of the Shiner Reservoir and Box Reservoir, reflecting the necessity of water storage on the arid Diamond Mtn slopes.
