The Little Malheur River carves through this high-elevation terrain along the border of Grant and Malheur counties. This 2014 survey captures a landscape defined by sharp volcanic features and drainage networks, including Clevenger Butte, Ironside Mtn, and Ring Butte. The western portion of the map is dominated by the Malhuer National Forest, where a network of forest service roads like NFD 16 Rd and Nat For Dev Rd 16 navigate the timbered slopes. Evidence of land use in this arid environment is found in the scattered improvements such as Black Pasture and Byars Spring, along with the small Lockhart Airport located near Bridge Cr. The topography is etched by seasonal watercourses including Deadwood Cr, Squaw Cr, and Little Lost Cr, providing a detailed look at the drainage patterns of the high desert plateau.
