The Columbia River serves as the dominant geographic and economic spine of this 2011 survey, marking the border where the Columbia Hills rise to the north and the high plateaus of Oregon stretch to the south. Central to the region's connectivity is Biggs Junction, a vital transit hub where routes converge near the southern end of the Sam Hill Memorial Bridge. On the Washington side, the settlement of Maryhill is situated along the riverbank, framed by the steep terrain of Henderson Canyon and Davies Pass.
