While sipping on a beer later that afternoon on the shore of Johnson Lake I described my ascent of Big Sister. “You mean like the Three Sisters?” Someone said. “Yeah”. “What are the names of the other sisters?” “Well there’s Big Sister, Middle Sister, and Little Sister”. “Are they harder to climb the bigger they get?” They asked. It is actually almost the other way around. Big Sister is a moderate scramble, Middle Sister is practically a hiking trail, and Little Sister is a technical climb. There are a few things that can turn you back on Big Sister however. If you follow the ridge route up, as described in Kane’s Scrambles book, which I highly recommend, then a down sloping rock band (crux) may be intimidating. I ran into a couple that had turned around at this point during a previous attempt. The crux can be avoided by traversing slabs to climber’s left, then getting back on route just above. The other thing that can turn parties around is a steep snow slope near the summit. Even with an ice axe, the angle is high and the potential runout could be deadly. I carried my axe, but as everything in the Rockies is nearly a month ahead of schedule this season, there was barely any snow remaining.
