Humphreys Peak (Hopi: Aaloosaktukwi, Navajo: Dookʼoʼoosłííd) is the highest natural point and the second most prominent peak after Mount Graham in the U.S. state of Arizona,[5] with an elevation of 12,637 feet (3,852 m)[1] and is located within the Kachina Peaks Wilderness in the Coconino National Forest, about 11 miles (17.7 km) north of Flagstaff, Arizona. Humphreys Peak is the highest of a group of dormant volcanic peaks known as the San Francisco Peaks.[6]

Humphreys Peak was named in about 1870 for General Andrew A. Humphreys, a U.S. Army officer who was a Union general during the American Civil War, and who later became Chief of Engineers of the United States Army Corps of Engineers. However, a United States General Land Office map from 1903 showed the name San Francisco Peak applied to this feature (apparently borrowed from San Francisco Mountain on which the peak stands). Thus the United States Board on Geographic Names approved the variant name in 1911. In 1933, the application of the names was rectified.[7]

Climate

The climate at the top of the mountain belongs to the dry-summer subarctic climate (Köppen: Dsc), close to the tundra climate (Köppen: ET), and the climate a little further down the mountainside is Hemiboreal climate (Köppen: Dsb) or warm dry-summer Mediterranean climate (Köppen: Csb). Six months of the year average temperatures below 32 °F (0 °C), and only July averages temperatures above 50 °F (10 °C). No month has a dew point higher than 32 °F (0 °C).
