Lower Sentinel Falls Ice Climbing, Yosemite. In January 1987, during an unusual cold snap, Ed Sampson and I climbed the lowest 750 feet of the frozen Lower Sentinel Falls. The ice was thin but well bonded to the wall. The route was repeated over the next three days by Jim Bridwell and Paul Tier, and then by Jay Smith and Paul Crawford. Six days after our ascent, major sections of the route fell off.
