Mount Lamarck lies on the crest of the High Sierra about 1 1/2 miles north of Mount Darwin. While easily climbed from the cross country trail over Lamarck Col ( class 2 ), Mount Lamarck also has a moderate ice gully on the North Face which provides excellent snow and ice climbing. The South Slope and Southeast Slope are also class 2.
Mount Lamarck has an excellent view of Mounts Darwin and Mendel!
Take Highway 168 from Bishop, CA. Follow the road to the North Lake trail head. Take the Lamarck Lake trail to Lower lamarck Lake. To climb the ice gully on the North Face, continue to Upper Lamack Lake. From here, rock hopping up the moraine past a glacial tarn leads to the pocket glacier at the base of the North Face.
For the class 2 route from Lamarck Col, leave the Lamarck Lakes trail between the Lower and Upper Lakes and head southwest along a faint path ( see R. J. Secors The High Sierra, Peaks, Passes and Trails guide book ).
The maps for this area are the Mt. Darwin and Mt. Thompson 7.5 minute USGS quadrangles.
