Located in Idaho and created in 1980, the Frank Church River of No Returns Wilderness is the largest contiguous area of protected wilderness in the continental United States at 2.3 million acres.
Inside the wilderness area, visitors find mountainous landscapes including deep canyons and white-water rivers. The Salmon River Canyon is one of the deepest gorges in the United States, with a depth larger than the Grand Canyon, but without the sheer walls.
The name of the area has two origins. First, the Salmon River was called the River of No Returns by early settlers who could navigate down the river, but were unable to make it back up due to the rapids. Frank Church was a US Senator who was instrumental in the protection of the area.
In conjunction with the nearby Gospel Hump Wilderness, the Frank Church Wilderness creates a 3.3 million acre roadless area. Just to the north, the Selway-Bitterroot Wilderness is only separated by a dirt road.
