Frank Church-River of No Return Wilderness
Public Land · Salmon, Idaho
Two million three hundred and sixty-six thousand acres of central Idaho mountain and river canyon - the largest contiguous federally managed wilderness in the United States outside Alaska. It spans six national forests and is cut through the middle by the Middle Fork of the Salmon and the Main Salmon, the river the fur trappers called the River of No Return because you could float down it and not get back up. It was designated in 1980 and named in 1984 for the Idaho senator who wrote the Wilderness Act's implementing law, weeks before he died. It is emptier than almost anywhere else in the lower forty-eight, and the way most people see it is from a raft.
