Humphreys Peak

Humphreys Peak is an extinct volcano in Coconino County, Arizona, rising to 12633 feet (3851 meters) above sea level. The summit forms the highest point in the state and sits within the San Francisco Peaks, a volcanic mountain range north of Flagstaff.

The mountain received its name in 1870 in honor of General Andrew Humphreys, who served as a Union commander during the Civil War. Humphreys later became Chief of Engineers for the Army and directed numerous mapping expeditions across the American West.

The Diné call this mountain Dookʼoʼoosłííd, referring to a summit that holds snow throughout the year. This name reflects the spiritual importance the mountain carries for many Native American groups across the Southwest.

The Humphreys Trail starts at Arizona Snowbowl and runs 4.75 miles (7.6 kilometers) to the summit, with the full hike usually taking between 6 and 8 hours. Hikers should begin early in the day since afternoon thunderstorms are common during the summer months.

Temperatures on the summit stay below freezing for roughly six months each year, with only July averaging above 50 degrees Fahrenheit (10 degrees Celsius). Hikers can experience warm weather at the trailhead and icy conditions at the top on a single summer day.
