Teton Range A lthough the 1937 clim bing season in the Tetons was shorter than usual (Ju n e 24th-September 17th), a large num ber of m o un taineers visited the region, concentrating upon G rand Teton and M t. Ow en. Six of the eight established routes on G rand Teton were utilized by various parties, while on M t. O w en four of the five known routes were employed. W ith the exception of M t. W iste r all of the m ajor peaks were climbed. The annual outing of the M azam as was held in late Ju ly , followed by the outing of C alifornia A lpine Club in early A ugust, both groups encamping at S tring Lake, w ith a total of more than 100 climbers and hikers. The guide service was again conducted by Paul Petzoldt, assisted by E ldon Petzoldt and Glenn E x u m . O n ly one original climb was reported— an ascent of G rand Teton from the head of Teepe Glacier on the S. W . side by W illia m House, Paul Petzoldt and the writer. Free of ice in late season, the route proved less difficult than anticipated and required little more than five hours from timberline. Descent was made by the E.-S. buttress, the route differing in part from that of 1931. A third ascent of the N . corner of G rand Teton (FryxellU nderhill, 1931) was accomplished by A dam s Carter and P aul Petzoldt; and the ascent of M t. O w en by the N . arête (FryxellF. Sm ith, 1931) was repeated by Jack Durrance, Percy R ideaut and George Sheldon. The approach to the arête, however, was made from the N . shoulder of G rand Teton, involving a first crossing of Gunsight Notch. P h i l D. S m i t h .
