Fall River drains the wild southwest corner of Yellowstone and comes down through lodgepole country into the Henrys Fork system. It's an overlooked freestone — rainbows and cutthroat in pocket water and runs that see a fraction of the crowd the famous Fork gets just over the hill. There's irrigation pull on the lower river, but up high it's lovely, lightly-fished water for an attractor dry. People drive right past it to fish the Railroad Ranch, which is fine by anybody who'd rather have it to themselves.
