The Frank Church River of No Return Wilderness in Idaho is made up of rugged mountains, deep canyons, and wild whitewater rivers, including the Main Salmon River and Middle Fork of the Salmon River. “Frank Church” was attached to the site’s name in honor of late U.S. Senator Frank Church, who played a leading role in its preservation. The area is the largest single connected wilderness in the contiguous States and contains four national forests.
