Carving through one of the deepest river gorges in North America, the Main Salmon River holds centuries of human history within its granite walls.
For over 8,000 years, the Shoshone, Bannock, and Nez Perce tribes lived along the Salmon River canyon. They established seasonal fishing camps, hunted native bighorn sheep, and left behind vibrant pictographs painted on cliff faces that remain visible to river travelers today.
In August 1805, Captain William Clark scouted the Salmon River looking for a water route to the Pacific Ocean. Driven back by impenetrable rapids and vertical canyon walls, he declared the river unnavigable—earning it the legendary name "The River of No Return."
During the late 19th-century gold rushes, miners and homesteaders built heavy wooden flatboats (scows) to haul supplies downriver. Because the rapids prevented upstream return trips, these boats were dismantled at their destination to construct cabins and mining shacks.
In 1968, the Salmon River was designated under the National Wild and Scenic Rivers Act. Today, it flows through the heart of the 2.3-million-acre Frank Church–River of No Return Wilderness—the largest contiguous roadless wilderness in the lower 48 states.
