Sonora Peak is a mountain in the Central Sierra Nevada of California north of Sonora Pass. Located on the boundary between Alpine and Mono counties, it is the highest point in Alpine County.[1] Due to the high elevation, most of the precipitation this mountain receives consists of snow.[4]
There is no weather station at the summit, but this climate table contains interpolated data for an area around the summit. Sonora Peak has a (subalpine climate (Köppen Dfc).
One of the most direct routes of ascent starts at Sonora Pass, 2 miles (3 km) south as the crow flies. Starting at the trailhead of the PCT on Sonora Pass, it is about a 2.5-mile (4.0 km) hike with 1,000 feet (300 m) elevation gain to the top of a pass. From there, the easiest and most direct way is to turn northwest and follow the ridge that will lead to the summit. About halfway from the pass to the peak a small trail appears that heads directly to the peak.[3] A second approach to the summit is from nearby Saint Mary's Pass trailhead. This trail approaches the peak from the other side of the mountain (the northwestern side) and is also a class 1 hike.
