Snake River canyon walls define the eastern border of this mid-century survey, marking the state line between Oregon and Idaho. The landscape is dominated by a succession of high ridges, including Sleepy Ridge, Jackey Ridge, and Windy Ridge, which separate deep drainages like Lightning Creek and Mormon Creek. High-elevation plateaus such as Lord Flat and Mormon Flat appear as significant grazing or transit points within the Wallowa National Forest.
