1981 Map of Clarkston

About this map

The Snake River serves as the dominant geographic and economic artery of this region, defining the border between Washington and Idaho at the confluence with the Grande Ronde River. The urban centers of Clarkston and Lewiston mark the northern gateway to the canyonlands, while the southern portion of the sheet is dominated by the high-elevation terrain of the Blue Mountains. This landscape is deeply incised by a complex network of ridges and gulches, including Pow Wah Kee Gulch and Smoothing Iron Ridge, which transition from agricultural plateaus to the protected timberlands of the Umatilla National Forest. The transportation infrastructure of the early 1980s is visible through the routes of the Union Pacific and the Camas Prairie Railroad, reflecting the area's history as a hub for moving goods from the Pataha Valley and surrounding uplands to the river ports.
