The San Francisco Peaks (Navajo: Dookʼoʼoosłííd, Spanish: Sierra de San Francisco, Hopi: Nuva'tukya'ovi, Western Apache: Dził Tso, Keres: Tsii Bina, Southern Paiute: Nuvaxatuh, Havasupai-Hualapai: Hvehasahpatch/Huassapatch/Wik'hanbaja, Yavapai: Wi:mun Kwa, Zuni: Sunha K'hbchu Yalanne, Mojave: 'Amat 'Iikwe Nyava)[2] are a volcanic mountain range in the San Francisco volcanic field in north central Arizona, just north of Flagstaff and a remnant of the former San Francisco Mountain. 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.[3] An aquifer within the caldera supplies much of Flagstaff's water while the mountain itself is in the Coconino National Forest, a popular recreation site. The Arizona Snowbowl ski area is on the western slopes of Humphreys Peak, and has been the subject of major controversy involving several tribes and environmental groups.[4][5]
