About this map

The Snake River carves a deep path through the Pacific Northwest interior on this 1981 survey, marking the jurisdictional convergence of Washington, Idaho, and Oregon. The urban centers of Clarkston and Lewiston serve as the primary hubs at this river junction, flanked by Clarkston Heights and the riverfront Hells Gate State Rec Area. The landscape transitions sharply from the agricultural Pataha Valley and settlements like Pomeroy in the north to the dense timber of the Umatilla National Forest and Wenaha-Tucannon Wilderness in the south.

Transportation networks define the region's economy, with US Highway 12 following the river contours and the Camas Prairie Railroad and Union Pacific lines providing critical industrial links. The map documents an intricate system of ridges such as Smoothing Iron Ridge and Tam Tam Ridge, alongside remote outposts like Peola. This survey captures the region just as modern recreation and wilderness designations were being codified alongside long-standing ranching and rail interests.
