Thomason Mine and Schwayder Mine sit in the northern high ground of this Malheur County landscape, marking the historical mineral interests that once drew prospectors to these slopes. The terrain is defined by a dense network of hydrologic features and springs, such as Cowboy Spring and Hole in the Ground Spring, which feed into major drainages like Bullrun Creek and the multiple forks of West Camp Creek.
