Bannock Ridge and the high desert terrain of eastern Malheur County are defined by deep canyons and prominent volcanic peaks in this 2017 survey. The landscape is marked by extreme elevation changes, rising from the floor of Craig Gulch and Moss Gulch toward landmarks like Smith Butte and the southern slopes of Mahogany Mtn. Human presence in this arid region is largely centered on water management and high-country access, visible through the Long Gulch Reservoir and Upper Saddle Butte Reservoir. Cattle ranching and back-country exploration are supported by a network of primitive tracks, including the primary Leslie Gulch Rd and the intriguing route known as The Whitenburg. Named springs such as Bannock Spring and Sulphur Spring provide critical landmarks for those navigating the ridges between Carter Cr and the heights of Steamboat Ridge.
