De Armond Mountain and Bendire Mountain dominate the high-elevation landscape of this Malheur County region. The topography is defined by a series of north-south running ridges, including Bendire Ridge and Lake Ridge, interspersed with flatlands such as Big Flat and the aptly named Poverty Flat. Water management is central to the area's geography, evidenced by a dense network of small catchments like Murphy Reservoir, Table Reservoir, and Goldy Reservoir. Larger water bodies such as Warm Springs Reservoir and the drainage of Warm Springs Cr suggest a landscape heavily modified for ranching or irrigation. Early transportation routes like Bendire Rd and Horseshoe Bend Rd thread through the canyons, connecting remote springs like Munkers Spring and Indian Spring. These scattered water sources and the varied terrain of Slaughter Gulch and Whitley Canyon highlight the logistical challenges of this high-desert environment.
