Twin Springs and a network of seasonal water sources define this high-desert landscape in Malheur County, Oregon. The terrain is characterized by complex drainages and volcanic features, from the elevations of Sourdough Mtn and Burnt Mountain down to the eastern edge of Lake Owyhee. Named springs like Whiskey Spring, East Spring, and Dead Horse Spring indicate the critical importance of water management in this arid region, further evidenced by the Dry Cr Buttes Reservoir to the south. The area's geography is deeply incised by Dead Horse Canyon and the winding course of Dry Creek, which eventually reach the reservoir waters. Primitive access routes such as the Dry Creek Cutoff and Twin Springs Rd connect these remote landmarks, tracing the historic movement of people through Sourdough Basin and Oxbow Basin.
