Towering above the Colorado Plateau to a height of more than 12,000 feet and visible from as much as 100 miles away, the San Francisco Peaks are believed to be the remnants of a large compound stratovolcano. Located due north of thePlateau’s largest city, Flagstaff, Arizona, an aquifer within the calderasupplies much of the city’s water while the mountain itself is the siteof much outdoor recreation.
Historically considered the Navajo’s Sacred Mountain of the West, herbal medicines have long been gathered in the high mountain peaks. Thediverse vegetation of the peaks gave origin to C. Hart Merriam’s Life Zonetheory, which describes the altitudinal zonation of both vegetation andanimal species.
