About this map

Malheur Reservoir dominates the northern high desert landscape, serving as a primary water source in this corner of Malheur County. The terrain is defined by a series of volcanic features and drainage networks, with Reservoir Butte standing prominently south of the reservoir and Cow Valley Butte marking the western hills. The southern reaches of the map reveal the expanse of Cow Valley, a geographic depression overlooked by Brogan Hill and its highest point at Brogan Hill Summit.

Transport through this isolated region follows historical corridors, most notably the Military Rd and Juniper Mtn Rd, which navigate the complex topography. A network of seasonal and perennial streams, including Cottonwood Cr and Cow Cr, suggests a land managed for ranching and water conservation, evidenced by smaller impoundments like Davis Reservoir Four. The map provides a clear view of the township and range grid system through labels such as t14s r41e, illustrating how the land was partitioned in this arid environment.
