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!

Getting There

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.

NW Lamarck

Hi There, I'd really like to move information from my existing “Northwest Lamarck” page to this page, and then delete my page. I don't think it really makes sense for them to be separate given the proximity of these two summits. Perhaps it might be sufficient to include one section labeled “Northwest Lamarck” on this page? Please let me know what your thoughts are on the matter. Thanks, - Chris

Re: NW Lamarck

Sure - ask a moderator the best way to do this. Craig

Re: NW Lamarck

As page owner, you can simply create a new section on the page and copy over whatever Schmed wants. I can do this as well if you're too busy but prefer to ask before going and messing with people's pages. Alternately, I could adopt this page if you're no longer interested in maintaining it. I climbed the peak last summer and could add some route details from the col and also update information about the trailhead, which is a pain to access unless you can snag a campsite at road's end.

Mt Lamarck from Lamarck Col

Greetings fellow mountaineers. I remember climbing this peak when I was in Troop 276 aka “The Mountain Men” from Palos Verdes Estates, CA back in August, 1977. I was 15 back then and a Star Scout. It was towards the end of our 8 day long term Sierra hike where we started backpacking from the Pine Creek trailhead and ended at North Lake, approx 75 miles total, half of the hike was cross country travel, part of it was on the John Muir Trail. What made this backpack trip very challenging was to go over several cross country passes, particularly Lamarck Col, with heavy external frame packs. The route we used started in Darwin Canyon, we scrambled up class 2 talus on the South side of Lamarck Col at approx 12,900 feet. From Lamarck Col we climbed up easy class 2 talus up the SSE ridge to the wide summit plateau, the true summit was further to the north. This was the first peak I climbed doing the sport of mountaineering off trail, I didn’t know what mountaineering was back then. I would rate this climb 4 out of 5 stars as it is a nice short scramble up the SSE ridge on stable class 2 talus and bracing and great views on the summit plateau; also it is an excellent 13,000 foot peak for beginning mountaineers to climb. The photos already posted (any that were shot from Darwin Canyon and the SE Ridge are helpful, there are over 100 photos) might be the best bet to document this particular route. Hopefully, I can find some photos, wait and see!

Children refers to the set of objects that logically fall under a given object. For example, the Aconcagua mountain page is a child of the 'Aconcagua Group' and the 'Seven Summits.' The Aconcagua mountain itself has many routes, photos, and trip reports as children.



Parents refers to a larger category under which an object falls. For example, theAconcagua mountain page has the 'Aconcagua Group' and the 'Seven Summits' asparents and is a parent itself to many routes, photos, and Trip Reports.
