Sonora Pass (el. 9,624 ft. / 2,933 m.) is the second-highest highway pass in the Sierra Nevada, lower by 321 ft. (about 98 m.) than Tioga Pass to the south. State Route 108 traverses the pass.
The pass connects the communities of Sonora to the west and Bridgeport to the east. Like most high Sierra Nevada passes, the highway is closed in winter, generally between November and May, due to snow accumulation. The highway over the pass is extremely steep (up to 26% in some locations), narrow and winding between Kennedy Meadows on the west side and Leavitt Meadows on the east. The route is not recommended for vehicles or vehicle combinations that are unusually wide, heavy or long.

Adjacent to the Pass is a picnic/parking area, which serves as a day-use rest stop or a trailhead for hikes to nearby Sonora Peak, Wolf Creek Lake, and other spots north or south along the Pacific Crest Trail. >>>> http://en.wikipedia.org/wiki/Sonora_Pass
