About this map

Lost Valley and its surrounding high-desert terrain in Owyhee County are defined by a network of seasonal drainages and vital water sources in this 2020 survey. The landscape is marked by the presence of Battle Cr, Big Springs Cr, and Blue Cr, which carve through the land between landmarks like Dollar Butte and the wide expanse of Bull Basin. The map captures a remote area where water management is crucial, shown by the infrastructure of Dry Cr Reservoir Number Four and Dry Cr Reservoir Number Seven in the northern reaches.

Transportation through this portion of Idaho is limited to rugged tracks such as Battle Creek Rd, which crosses the terrain near the Twin Bridges junction. Key hydrologic features for local ranching or navigation include Lost Valley Springs, Wildhorse Spring, and Upper Lost Valley Spring, providing specific points of reference for those tracing the history of land use in this sparsely populated region.
