Ascent Trip ReportNamed after Alexander G. McAdie, a scientist and writer in charge of the U. S. Weather Bureau in San Francisco, 1903-13; and later a professor of meterology at Harvard, 1913-31. Noted in "Sierra Club Bulletin", vol. 5, no. 4, June 1905. The first ascent was made by Norman Clyde in 1922. (Clyde, p. 78)
Mt. McAdie lies on the boundary of the Sequoia National Park (to the west) and the John Muir Widerness area of the Inyo National Forest. A permit is required for dayhikes and overnight trips on the Mt. Whitney trail used for the approach to this peak. Obtain a permit at the Inyo National Forest office, P. O. Box 8, Lone Pine, Ca. 93545. (760) 876-5542
The peak can be climbed in a long (11 to 13 hours) hike from the Mt. Whitney trailhead at Whitney Portal, which is 12.1 miles west of Lone Pine on the Whitney Portal road. Follow the excellent Mt. Whitney trail for about five miles to the switchback just before Consultation Lake. At this point leave the trail and go south across the stream and ascend the slabs on the east side of the lake. Continue along the lake then up the talus slopes to Arc Pass. From Arc Pass head west up the prominent talus slope that leads to the middle summit of McAdie. About half way up move to the right into the deep chute that leads to the notch between the middle and north summits. This is easier than the route that goes nearly to the top of the middle summit and then down to the notch described in "The High Sierra" by R.J. Secor, p. 45. From the notch follow the route described by Secor which goes around the NW side of the north summit. There are some 3rd class moves before reaching the easier upper slopes. There are outstanding views of Mt. Whitney from the summit. A low 5th class climb up the NE face is described in the "American Alpine Journal", 1979, p. 189. Nearby peaks to the east are Mt. Irvine and Mt. Mallory. Elevation gain from Whitney Portal is about 5470 ft. and the one-way distance is 6.3 miles. 9/93 RLC
