The Sheepshead Mountains define this high-desert landscape in southeastern Oregon, where the boundary between Harney and Malheur Counties cuts through a series of significant volcanic uplands. The terrain is marked by distinctive flat-topped landmarks like Table Mtn, which is surrounded by several catchments including N Table Mountain Reservoir and W Table Mountain Reservoir. This area is part of a complex system of rangeland water management, characterized by numerous small reservoirs and named springs that sustain life in the arid basin.
