The Snake River in the center of the picture is located at the confluence of the Snake River and Clearwater Rivers. Lewiston, Idaho is on the left; Clarkston, Washington on the right. Because of dams (and their locks) on the Snake and Columbia River, Lewiston is reachable by some ocean-going vessels. The Port of Lewiston (Idaho's only seaport) has the distinction of being the farthest inland port east of the West Coast. The viewpoint is 1,000 feet (30,480c) higher than the rivers below.
