The Deschutes River serves as the primary geographic and political boundary in this region, dividing Wasco and Sherman counties as it carves through deep canyons. The transport infrastructure follows these natural corridors, most notably with the Oregon Trunk Railroad hugging the western riverbank. To the east, the plateau landscape is defined by agricultural and rail-oriented settlements like Erskine, where the Union Pacific line runs parallel to established roadways.
