The Columbia River dominates this 2011 survey, serving as the border between Washington and Oregon. On the northern bank, the small community of Paterson sits beneath the rising Paterson Ridge, supported by agricultural infrastructure such as the Columbia Crest Winery Airport. Across the water, the settlement of Irrigon in Morrow County, Oregon, shows a dense grid of residential streets including W Oregon Ln and W Idaho Ln. The river itself is fragmented by large landforms like Big Blalock Island and Monument Island, while the southern shoreline is defined by complex waterways including McCormach Slough and Paterson Slough. This landscape illustrates the modern development of the Mid-Columbia region, where irrigation and transportation networks like Paterson Ferry Rd connect the high desert communities to the vital water resources of the river basin.
