The Columbia River forms a massive hydrological boundary between Oregon and Washington in this 2014 survey, where the town of Irrigon sits along the southern shore. The landscape is defined by the contrast between the vast waters of Lake Umatilla and the engineered agricultural systems inland, most notably the W Extension Irrigation Canal which traverses the terrain south of the river. The map details the residential core of Irrigon, showing a grid of streets including NE Washington Ave and E Idaho Ave near the Desert Lawn Memorial Cem. Across the Irrigon Middle Range Channel to the north, the Washington side transitions into an industrial and transport corridor featuring Wa-14 and the Plymouth Industrial Rd, set against the backdrop of significant geographical depressions like Bing Canyon and Fourmile Canyon.
