Lamarck Col to Evolution Lake

The Lamarck Col to Evolution Lake is an extraordinary and challenging 20 mile out-and-back route for those seeking to explore one of the most beautiful and popular basins in the Sierra Nevada while avoiding the major crowds. This trail offers a rewarding blend of alpine scenery, rugged terrain, steep climbs, and serene alpine lakes. Ideal for experienced hikers, this round-trip trek provides an immersive experience in one of the Sierra's most picturesque regions.

DESCRIPTION
The journey begins at the Lamarck Col Trailhead, located at the end of the road past North Lake Campground. This trailhead is shared with the Piute Pass Trail. The initial section of the trail climbs steadily through lush meadows and pine forests, gradually gaining elevation and increasing in steepness.

You’ll pass Upper Lamarck Lake and eventually enter an open alpine area with expansive views. Lamarck Col, the actual pass, sits above an unnamed lake.  From there, the rugged path to the pass is in sight. Though unmaintained, the use trails are easy to follow and are marked on OnX topo maps. You will then reach Lamarck Col, the high point of the trail. The view from the col offers a dramatic vantage point over Owens Valley to the east and the rugged terrain of the Sierra Crest to the west, north, and south.

From Lamarck Col, descend via Darwin Bench into the Evolution Basin, characterized by its striking granite formations and pristine alpine lakes. The trail meanders through this high-altitude environment, featuring occasional rocky sections and uneven footing.

Eventually, you will reach the Pacific Crest Trail (PCT), a well-maintained singletrack that follows the eastern shore of Evolution Lake. As you approach the lake, the scenery becomes increasingly spectacular, with crystal-clear waters reflecting the rugged peaks that surround it. Evolution Lake is a great place to spend time and a prime spot for camping.

The return hike retraces the same route back to the Lamarck Col Trailhead and North Lake Campground.

Flora and Fauna
Throughout the hike, you'll encounter a range of Sierra flora, including alpine wildflowers, pine forests, and meadows. Wildlife sightings may include mule deer, marmots, and a variety of bird species. This area is known for active black bear activity, so proper food storage is required.

PARKING
Day use and overnight parking is available at the trailhead. 

Considerations

• Water: Carry enough water for the entire hike or be prepared to treat water from streams along the way.

• Weather: Weather conditions can change rapidly in the Sierra. Be prepared for varying temperatures and possible thunderstorms.
