Humphreys Peak (12,633ft = 3,851m) is the highest point of San Francisco Mountain. It is also Arizona's only stratovolcano.
San Francisco Mountain is considered Mt. Saint Helens twin because the appearance of both San Francisco Mtn. and Mount Saint Helens is remarkably similar when viewed from looking into both of their bowls.
