Sharkfn Tower, Northwest Face. On July 1, Dan Raish, Woody Savage and I made the first recorded ascent on the north side of this small but prominent peak above Boston Basin. A drop over Sharkfin Col and a short traverse to the east on the Boston Glacier brought us to a steep ice tongue leading up the northwest rib of the tower. After three 150-foot leads on 50°-60° névé, the crest of the arête was reached and the remaining 500 feet were all on the excellent Sharkfin quartz diorite. Climbing was all moderate class 4 with one class 5 lead required to exit from the rib onto the upper north face. This mixed ice and rock route has the advantage of a much more spectacular alpine setting than the more direct south side approaches. Seven hours were required from upper Boston Basin.
