Cottonwood Mountain stands as the central topographic focal point of this Malheur County landscape, where a sophisticated network of ephemeral water sources and springs sustained high-desert activity. The map reveals a reliance on vital water points such as Chokecherry Spring, Grey Horse Spring, and Antelope Spring, which are scattered throughout the drainages. Man-made interventions in the hydrology are evident at the Upper Buckbrush Reservoir and the primary Buckbrush Reservoir, indicating managed water resources for livestock or land use in an otherwise arid environment. Navigation across this terrain is defined by a handful of established tracks, including Juniper Mtn Rd and Dry Creek Loop Rd. The area is further characterized by distinct flats and gulches, such as Thorn Flat, that break the elevation patterns of the surrounding ridges and creeks like Brady Creek and Brian Creek.
