Mounts “Petrie,” “Plaskett,” and Walrus. From a base camp on the shore of Dimsdale Lake near Gray Pass in the northermost British Columbia Rockies, George and Marcia Wallerstein, Bob O’Dell, Tom Grenfell, Lyman Spitzer, and I made three first ascents. Since we were all astronomers and only Mount Walrus was named on the map, we decided to call the other two peaks after past directors of the Dominion Astro-physical Observatory in Victoria, B.C. Mount Petrie (9400 feet) was situated immediately east of the lake, so that we had an easy conquest on July 25 by the east ridge in eight hours from our camp. The route to Mount Walrus (9100 feet), however, took 2½ days of exhausting bush whacking to descend to Jarvis Creek and then establish a camp on the west shoulder of the mountain. From there the ascent up the south ridge on July 29 took 6½ hours. Rainy weather added variety to the return trip through the bush to our base camp. For Mount Plaskett (9600 feet), which lies to the west of Petrie, we carried a camp to the glacier flowing north from the col between the two peaks. We climbed the middle summit of Plaskett on August 6 in 6½ hours by the easy slopes on the west face.
