2014 Map of Twin Buttes

About this map

Twin Buttes rises above a high-desert landscape defined by complex water management and drainage systems in southeastern Oregon. This 2014 survey documents a network of named waterholes and reservoirs essential for ranching and wildlife, such as Mammoth Waterhole and Horse Haven Reservoir. The terrain is characterized by the prominent Black Rim and the seasonal flows of Jackass Creek. The map shows how early 21st-century infrastructure utilized natural depressions and canyons for water storage, naming features like Rocky Hole Reservoir and Middle Butler Reservoir. Settlement is sparse, with Catlow Rd providing one of the few primary access points through this arid region. The distribution of features like Griffen Waterhole and Toohey Waterhole reveals the vital importance of every water source across the high plateau.
