1982 Map of Rattlesnake Canyon

About this map

Potomac Ranch and Bowden Ranch anchor this high-desert landscape in southeastern Oregon, where water management is central to the area's survival. The map reveals a complex network of seasonal drainages and man-made impoundments, such as the Bull Creek Reservoir and Holding Corral Reservoir, designed to support livestock across the arid terrain. The physical geography is dominated by the deep incisions of Rattlesnake Canyon and Wooyhawk Canyon, while prominent elevations like Jackies Butte and Little Grassy Mountain provide essential navigational landmarks.
