2020 Map of McCain Creek

About this map

McCain Creek winds through this high-desert landscape of southeastern Oregon, defining a drainage system punctuated by numerous reservoirs and springs. The terrain is marked by significant landmarks like Mahogany Mtn and the unique formation known as The Tongue. Historical water management is evident throughout the quadrangle, with multiple catchments such as McCain Reservoir Number One and McCain Reservoir Number Two supporting the arid environment. These water sources, along with Upper McCain Springs and Lower McCain Springs, provided essential anchor points for ranching and land use in this corner of Malheur County. Isolated access routes like Mahogany Rd and Blowout Reservoir Rd traverse the high country, connecting the reservoirs to the broader geographic features like Gunsight Pass and Hon Gulch.
