The Columbia River serves as the dominant boundary on this 1980 survey, where the Washington Oregon state line follows the water's path through the Columbia Hills. To the north, Goldendale sits as a regional hub near the Little Klickitat River, while the southern reaches across Sherman Co and Gilliam Co reveal a high desert landscape of expansive flats and deep canyons. The river corridor itself shows a sophisticated mid-century transportation and energy network, featuring the John Day Dam and the transition from Lake Cellilo to Lake Umatilla. Small railroad settlements and cultural landmarks like the Maryhill Museum and Wishram anchor the shoreline, while the upland interior is marked by agricultural outposts such as Bickleton and Cleveland at the edge of the Simcoe Mountains. This map documents the region's character as a major transit corridor for the Burlington Northern and Union Pacific railroads.
