Harney Valley defines the core of this landscape, where a complex network of sloughs and river forks converge within the broader Harney Basin. The hydrology is particularly intricate, dominated by the diverging channels of the West Fork Silvies River and East Fork Silvies River, alongside numerous seasonal watercourses like Boat Ford Slough and McRae Slough. This network suggests a land managed for its water resources, supporting the local ranching tradition.
