Owyhee River carving through the high desert of Malheur County defines this landscape, where the confluence of several forks creates a complex network of canyons and plateaus. The convergence near Three Forks Rim and Three Forks Dome is marked by geothermal activity at Tudor Warm Springs and the Three Forks Hot Springs Trl. A legacy of high-desert ranching and water management is evident in the numerous upland catchments like Whitehorse Cr Reservoir and Porcupine Reservoir. The steep ascent of Military Grade suggests the challenging historical transit through this terrain, connecting the river valley to the broad expanse of Tuu-Tipi Flat. This modern survey documents a preserved riparian corridor protected as the Owyhee Wild and Scenic River.
