1968 Map of Piute Reservoir

About this map

Guano Valley and the surrounding high desert of Lake County are defined by a network of seasonal water management and remote ranching outposts in this late 1960s topographic study. The landscape is punctuated by essential catchments such as Piute Reservoir and Barry Reservoir, which capture the intermittent flows of Piute Creek and Jack Creek to support the local livestock economy. Settlements are sparse, represented by isolated landmarks like Barry Ranch and Doherty Ranch, which serve as the primary human touchpoints in this arid environment. A significant portion of the southeastern quadrant is dedicated to the Charles Sheldon Antelope Range, indicating the region's importance for wildlife conservation and land management. The presence of numerous Jeep Trails and a localized Borrow Pit suggests a pattern of movement and maintenance necessary to sustain these remote ranching operations across the high basin terrain.
