San Francisco Peaks
The San Francisco Peaks are a volcanic mountain range located in north central Arizona, just north of Flagstaff. The highest summit in the range, Humphreys Peak, is the highest point in the state of Arizona at 12,633 feet (3,851 m) in elevation. The San Francisco Peaks are the remains of an eroded stratovolcano. An aquifer within the caldera supplies much of Flagstaff's water while the mountain itself is located within the Coconino National Forest and is a popular site for outdoor recreation. The Arizona Snowbowl ski area is located on the western slopes of Humphreys Peak, and has been the subject of major controversy involving several tribes and environmental groups.
The mountain provides a number of recreational opportunities, including wintertime snow skiing and hiking the rest of the year. Hart Prairie is a popular hiking area and Nature Conservancy preserve located below the mountain's ski resort, Arizona Snowbowl.
Humphreys Peak (latitude 35°20'47" N) and Agassiz Peak (latitude 35°19'33" N) are the two farthest south-lying mountain peaks in the contiguous United States which rise to a height of more than 12,000 feet above sea level.
Prior to its collapse due to a lateral eruption to the northeast (around 200,000 years ago) and subsequent glacial erosion, the San Francisco Peaks fully matured elevation is interpreted to have been around 16,000 feet above sea level
