Grand Canyon National Park Arizona
The Grand Canyon was formed by 5-6 million years of erosion as the Colorado River craved its way through multiple layers of rock. The Grand Canyon is approximately 277 miles long. Its deepest point from the rim to the river is 6000 feet. It was designated a National Park in 1919 and receives nearly 5 million visitors a year.
Thanks to Roger :)
