San Francisco Peaks
In the distance you can see Humphreys Peak,
the highest point in Arizona at 12,633 ft
(3851m). Forty-eight miles south of here,
Humphreys Peak is one of a series of mountains
known as the San Francisco Peaks, which once
were active volcanoes. Geologically young, the
peaks formed in the past six million years or so
and have been active as recently as 1000
years ago.
