2017 Map of Wallula

About this map

The Columbia River carves a dramatic path through this 2017 study of the Washington-Oregon border, where the river narrows at the iconic Wallula Gap. This geologically significant area serves as a vital transportation corridor, connecting the settlements of Wallula, Attalia, and Wallula Junction along the eastern bank. The confluence of the Walla Walla River and Lake Wallula dominates the central landscape, while the Horse Heaven Hills rise to the west. Industrial and agricultural infrastructure is evident in the presence of Port Kelley and the Columbia Canal Number 3. Cultural landmarks include the Madame Dorion Bridge and the Wallula Horse Trail, which reflect the region's layered history of transit and recreation near the basalt formations of the Twin Sisters.
