Fossil Springs Wilderness

"Where there is water, there is life," the saying goes, and Fossil Springs proves it's true every day of the year. At the bottom of a steep and wide canyon, at the edge of the Colorado Plateau just south of the Mogollon Rim, a group of springs pump water to the surface at the rate of about 20,000 gallons per minute. That endless water supply supports one of the most diverse riparian ecosystems in the state–more than 30 species of trees set among native desert shrub. It also creates a haven for abundant wildlife: elk and deer higher up; javelina, coyote, skunk, ring-tailed cat, fox, and smaller mammals lower down; and more than 100 species of birds.
