Agassiz Peak is the second highest mountain in U.S. state of Arizona at 12,356 feet (3,766 m). It is located in the San Francisco Peaks within the Coconino National Forest near Flagstaff, Arizona. The peak was named for Louis Agassiz, the celebrated naturalist.
Many visitors to Flagstaff incorrectly assume that Agassiz Peak is Humphreys Peak. This is because Agassiz is between Humphrey and Flagstaff, blocking the view of Humphrey from town leading many to make this incorrect conclusion.
The mountain is open to climbers only in the winter when it is covered in snow. Hiking above treeline at other times is illegal due to the "threatened with critical habitat" status of the San Francisco Peaks Groundsel (Senecio franciscanus).
