Arizona Snowbowl is located on the western slope of Mount Humphreys, the tallest point in the state. Humphreys is the most recognizable point on the San Francisco Peaks, which are north of Flagstaff. "The Peaks," as they are often known, are what remains of an eroded, dormant stratovolcano that was formed between 500,000 and 1,000,000 years ago.
