The John Day River winds through this rugged section of Grant County, where the high peaks of the Aldrich Mountains dominate the southern half of the landscape. Within the boundaries of the Malheur National Forest, the terrain is defined by steep ridges and drainages like Schoolhouse Gulch and Gray Gulch. A significant point of local history is the Aldrich Grave, situated near the Cheechako Ranch and the Stewart Ditch, which suggests early ranching and water management efforts in this canyon environment.
