Grand Canyon National Park is probably the most sensational example of erosion anywhere in the world. Encompassing 277 miles of the Colorado River and adjacent uplands,. the canyon is 10 miles across and more than a mile deep, displaying 2 billion years of geologic time. The South Rim park entrance is 80 miles northwest of Flagstaff, Arizona.
Our panoramic view of the Grand Canyon is taken from the South Rim at Yaki Point, just a mile east of the Visitor Center. From an elevation of 7,262 feet, we look northeast up the canyon, then turning left (north, then west) our view passes over South Kaibab Trail, the western portion of the canyon , then Yavapia Point and Park headquarters.
