With frozen roads blocking our penciled path through Yellowstone, we decided to head west and south, into the Caribou-Targhee Nat’l Forest. Henry’s Fork of the Snake River tumbles through, and a site next to the trout-brimming tributary called the Warm River provided us a chance to chill. Not that we did, of course….
Once we were at river’s edge, we spied heavy timbered woodwork on the cliff’s edge, about 300 feet above us. Denver clambered with us as we scrambled over the talus slope only to find the wood was old tunnel member where the Union Pacific cut a 600′ tunnel through the mountain at this particularly crumbly point.
