Longs Peak Trailhead: Chasm Lake, Rocky Mountain National Park, Colorado
Longs Peak Trailhead: Chasm Lake
Rocky Mountain National Park
In a deep cirque basin enclosed by the steep flanks of Mt Meeker (13,911'), Longs Peak (14,259') and Mount Lady Washington (13,281') sits Chasm Lake, a strikingly beautiful alpine lake in the upper-reaches of a rugged glacial gorge. Dramatically rising some 2,456 vertical feet above the center of Chasm Lake is Longs Peak's iconic, northeast-facing 'Diamond'.
