The Columbia River serves as the dominant geographical and political boundary here, separating Washington and Oregon while defining the local economy of the Mid-Columbia region. In the northern section, the high ground of Canoe Ridge and Quarry Butte overlooks the river, while the settlement of Whitcomb sits near the tracks of a major rail line and Whitcomb Island. This landscape is marked by the distinct topographic features of the basalt plateaus, including the prominent Crow Butte rising from the riverbed and the deep scars of Artesian Coulee and Dead Canyon. On the southern Oregon shore, the terrain transitions to a managed agricultural and transportation corridor. The W Extension Irrigation Canal winds through the landscape south of the Boardman Airport, illustrating the extensive water management systems required for farming in this arid environment. The road network, including Wa-14 and Tower RD, connects the scattered farmsteads and rural infrastructure that define this borderland region.
