About this map

Black Leg Creek and its tributary Cottonwood Cr carve through this high-elevation corner of Owyhee County, defining a landscape of intermittent drainages and critical water sources. The map reveals the ranching and livestock infrastructure essential to the region, centered on the Black Leg Reservoir and Billings Reservoir. These man-made features, alongside natural points like Rizzi Spring and Willow Spring, represent the vital water network of the J-P Desert plateau.

Landforms such as Black Leg Box Canyon and Sheep Trail Canyon illustrate the erosional character of the high desert, while the prominence of Bull Creek Point offers a clear topographic landmark. The lone primary artery, Rowland Rt Rd, provides the only significant access through this remote range, connecting dispersed features like Rattlesnake Draw and Whiskey Draw. This 2017 survey documents the modern state of these public and private lands, noting the continued importance of springs and draws in the Idaho desert.
