Night Cap PeakNight Cap Peak is a mountain summit located in Tuolumne County, California, United States.DescriptionNight Cap Peak is set along the boundary of the Emigrant Wilderness on land managed by Stanislaus [National Forest]. The peak is part of the Sierra Nevada mountain range and is situated 2.6 miles northwest of Leavitt Peak, and three miles west-southwest of Sonora Pass. Topographic relief is significant as the summit rises over above Kennedy Meadow in three miles. Precipitation runoff from this mountain drains into Kennedy and Deadman creeks which are tributaries of the Middle Fork Stanislaus River.EtymologyThe peak was named "Night Cap" in the 1890s by the United [States Geological Survey|USGS], presumably because of its resemblance to a nightcap. The landform's present toponym was officially adopted in 1979 by the U.S. Board on Geographic Names.ClimateAccording to the Köppen climate classification system, Night Cap Peak is located in an alpine climate zone. Most weather fronts originate in the Pacific Ocean, and travel east toward the Sierra Nevada mountains. As fronts approach, they are forced upward by the peaks, causing moisture in the form of rain or snowfall to drop onto the range.
