The Okanogan River corridor defines the eastern edge of this landscape, where the settlement of Riverside sits at the junction of Tunk Creek Rd and Us-97. This region is characterized by a high density of small, often saline-named water bodies such as Poison Lake, Alkali Lake, and Medicine Lake, which are scattered throughout the basin west of the river. The name Wagonroad Coulee suggests the historical movement of goods and people through these dry drainage channels, connecting the valley floor to the higher elevations of Chilson Mtn and Cave Mtn.
