As sunrise begins to show the first light of day, hikers take their first steps through geological time in what is known as one of the Seven Wonders of the World. Here among the rocks of a magnificent mile deep gorge on the South Kaibab Trail along the South Rim of Grand Canyon National Park one starts a journey through time. Hikers step off onto the trail at an elevation of 7,250 feet (2,200 meters). The trail is steep, descending 4,860 feet (1,481 m) in just 6.3 miles (10.1 kilometers) to the Colorado River at the bottom of the canyon.
