About this map

Lost Valley Springs and the surrounding high-desert range of Owyhee County define this 1972 landscape, revealing a remote territory shaped by water management and transit. The map documents a network of livestock or irrigation infrastructure, including Dry Creek Reservoir No 4, Dry Creek Reservoir No 7, and Dry Creek Reservoir No 6. These water sources are connected by a system of primitive routes such as the Jeep Trail and a significant north-south Pipeline through Lost Valley.

Evidence of historical activity is found near the Upper Battle Creek Crossing, where unnamed ruins sit along the banks of Battle Creek. This area, characterized by geological landmarks like Dollar Butte and the broad Bull Basin, shows the vital importance of seasonal water for those moving through the region. Named crossings such as Twin Bridges and Blue Creek Crossing highlight the primary points of passage for those navigating this expansive terrain.
