Grand Canyon

Grand Canyon Travel Guide

Grand Canyon National Park is a superstar -- biologically, historically, and recreationally. One of the world's best examples of arid-land erosion, the canyon provides a record of three of the four eras of geological time. In addition to its diverse fossil record, the park reveals prehistoric traces of human adaptation to an unforgiving environment. It's also home to several major ecosystems, five of the world's seven life zones, three of North America's four desert types, and all kinds of rare, endemic, and protected plant and animal species.
