About this map

O X Lake and the surrounding high plateau of Owyhee County characterize this arid interior landscape as it was documented in the early 1970s. The region is defined by a sophisticated water management network essential for livestock and ranching, featuring numerous high-elevation catchments such as Whickney Tree Reservoir, Shearing Corral Reservoir, and the Twin Lakes Res. This infrastructure, alongside named water sources like Little Tigert Spring and Tigert Spring, suggests a landscape organized around seasonal grazing and range management.

Topographically, the area is dissected by deep drainage systems including Perjue Canyon and Halfway Gulch, which feed into larger watercourses like Jacks Creek. Access through this remote terrain was maintained via the Perjue Jeep Trail and other unimproved tracks, reflecting the limited but vital transportation network used by land managers and locals before modern development altered the high desert character of Horse Basin.
