Thirtymile Cr carves a winding path through this corner of Gilliam County, anchoring a landscape defined by deep drainages and volcanic rises. The topography is a complex network of branching coulees, including the central Schott Canyon and the evocatively named Coffin Canyon and Sniption Canyon. High points like Coyote Butte and Zero Butte provide orientation across the high plateau, while named ridges such as Shoestring Ridge and Stebins Ridge separate the various watersheds.
