The high desert borderlands of Oregon and Idaho define this 2014 survey, where livestock management and water access dictate the landscape. Situated in Malheur County, the terrain is shaped by a network of ranching infrastructure including the Last Change Reservoir, Stearns Reservoir, and Hooker Reservoir. The drainage of Hooker Creek and Cow Cr moves through a series of ridges and basins, with Spring Mtn and Purser Ridge serving as prominent landmarks. Transportation across this arid plateau relies on corridors like the Ion Hwy and the Silver City Cutoff Rd, which follow ancient pathways through the sagebrush. Named water sources such as Poacher Spring and Bennett Spring highlight the critical nature of reliable water in this remote corner of the Owyhee country.
