The Grand Canyon is a steep-sided canyon carved by the Colorado River The Grand Canyon is 446 km long, actually is an extension of the Glen Canyon at the outlet of Lake Powell. Grand Canyon is up to 29 km wide and in some places are 1,850 meters deep. The canyon is one of the most iconic places in the whole of the US. The visitor center is at the south rim. When we visited in April 1971 the temperature at this elevation (2100 m) was one night below freezing.
Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted.
For thousands of years, the area has been continuously inhabited by Native Americans, who built settlements within the canyon and its many caves. The Pueblo eople considered the Grand Canyon a holy site, and made pilgrimages to it.
