The San Francisco Peaks (Navajo: , , 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) are a volcanic mountain range in north central Arizona, just north of Flagstaff. Part of the San Francisco volcanic field, the Peaks are the remnant of the former San Francisco Mountain, a prehistorically larger single stratovolcano. The highest summit in the range, Humphreys Peak, is the highest point in the state of Arizona at in elevation. 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.
