Mt. Conness from Polly Dome
Northeast to Mt. Conness.  Polly Dome  summit above big white rock.
Polly Dome is a large complex dome on the northwest side of Tenaya Lake in the Yosemite high country. The glaciated and exfoliated southeast portion of the dome, known as Stately Pleasure Dome is a prominent sight next to motorists on Hwy. 120 as they drive around the northwest shore of the lake. The dome is over 2 miles long and has forested north and west slopes. Stately Pleasure Dome has 10 class 5 climbing routes featured in the previous link. The rest of the larger dome has a few class 2 routes to the top and at least 4 class 5 climbing routes. The summit has unobstructed views north over Tuolumne Meadows to the Sierra crest, northwest over the Grand Canyon of the Tuolumne and east to the Cathedral Range.
