Buckbrush Poison Butte dominates the central landscape of this Malheur County high-desert terrain, standing as a prominent landmark among a series of uniquely named volcanic features including Big Poison Butte and Little Poison Butte. The drainage system is defined by the winding course of Buckbrush Cr and Dry Cr, which feed into vital water sources like the Soldiers Canyon Reservoir and N G Cr Reservoir. This area reflects a classic Great Basin ranching and grazing environment, where the locations of water sources such as Upper Mud Spring, Chalk Spring, and North Salter Spring were critical for survival. High-altitude flats like Richie Flat and deep incisions like Timber Canyon illustrate the topographical variation of the eastern Oregon rangelands before they descend toward the Bully Creek Rd corridor.
