Sharkfin Tower is an incredible rocky peak amongst some large glaciers. The climb has solid rock that is very exposed and the views to the north are staggering. The climb starts with a fairly rigorous climber’s trail on day 1 to gain Boston Basin. Starting at about 3200′, this “trail” goes up some very steep wooded terrain, over logs and crosses some rushing creeks and finally opens up into some spectacular alpine terrain at about 5200′. There are few campsites to choose from, but our personal favorite is up at 6200′ below Forbidden Peak.
On day 2, we’ll rise early, scramble the moraine, and attain the Quien Sabe Glacier. This will be some fairly straightforward glacier travel to get to the base of the tower. After some scrambling, a bit more steep snow climbing, and a few pitches of spectacular 5th class rock climbing we’ll be standing on the top of the summit. For fit climbers, it is possible to climb both Sharkfin Tower and Sahale Peak on the same day.
On day 3, we can climb another objective, go over skills, or just hike out.
