This area has been described as the most diverse riparian area in Arizona. Over thirty species of trees and shrubs and over a hundred species of birds have been observed in this unique habitat. The stream seems to appear out of nowhere, gushing 20,000 gallons a minute out of a series of springs at the bottom of a 1,600 foot deep canyon. Over the years these calcium laden waters have laid down huge deposits of a material called travertine. That rock-like substance encases whatever happens to fall into the streambed - forming the fossils for which the area is named.
Most people come to Fossil Creek to sunbathe, wade, hike and birdwatch. It's also a great place to take photographs. The lushness of the riparian area strikes a sharp contrast to the brittle desert that surrounds it. While you're here, keep an eye out for javelina. These collie dog-sized wild pigs are plentiful in the area.
