Mount Lefroy, First Winter Ascent. After snowshoeing across Lake Louise, the climb to Abbott Pass was hard trail-breaking. A cold, windy day kept us stormbound among the blankets of Abbott Hut. On March 24 Jim Madsen, Ron Burgener and I climbed Lefroy via the standard route. The howling, cold wind added zest. Crampons usually bit in well, although some powdery areas required careful belaying.
