Mammoth Crest is a climbing area in the Mammoth Ranger District of Inyo National Forest in California, managed by the Forest Service. It sits among a cluster of climbing and hiking destinations, with Labor Wall about 0.2 miles away and McLeod Lake about half a mile off. The area is known for its alpine routes, and 18 climbing routes are listed here, all in the alpine style. Grades run from 5.8 up to 5.11b, with the median around 5.10b. Some of the named routes include Finger Locking Good at 5.8, Backseat Climber at 5.10b and A Good Ribbing at 5.11b. Summer is the most comfortable time to visit. Typical averages from a nearby weather station at Tuolumne Meadows show July highs around 71°F and lows near 38°F, though that station sits well below the area, so temperatures at Mammoth Crest run cooler.
