Mount Lamarck

Post by artrock23 » Sun Jul 07, 2013 12:46 pm

TITLE: Mount Lamarck

GENERAL OVERVIEW: Situated at the northern end of the Evolution Region, Mt. Lamarck is the peak just directly north of a popular trans-Sierra route where it crosses Lamarck Col. It has a large summit plateau with five distinct high points. From North Lake trailhead and Upper Lamarck Lake, it is distinguished by it's long flat summit ridge with a v-notch (North Couloir) towards it's southern end. Note that the summit register is notoriously difficult to locate, as there is ongoing debate about the true highpoint of this peak. There are excellent views of Mt. Darwin, Mt. Mendel, and other high peaks from the summit.

CLASS/DIFFICULTY: Class 2 from the South slope. Class 2-3 from the Southeast slope. The ridge from Lamarck Col is Class 3. The North Couloir is Class 4 which involves snow/ice.

LOCATION: Inyo National Forest, John Muir Wilderness.

ELEVATION: 13,417 ft.


ROUTE DESCRIPTION: From the North Lake trailhead (i.e. parking area), approximately 3 miles to Upper Lamarck Lake, then approximately 2.5 miles via an unmaintained trail to Lamarck Col. Can also be approached from the west from Darwin Canyon. The designated summit is approximately 1/2 mile north of Lamarck Col.
