Grand Canyon, Arizona, USA
The Grand Canyon is a colossal canyon system in Arizona in the United States that has been eroded by the Colorado River and its tributaries during the uplift of the Colorado Plateau. The Grand Canyon is 446 km long and up to 29 km wide, and reaches a depth of over 1.6 km at its deepest point. In this giant scar across the land, almost 2 billion years of geological history are revealed in well-preserved stratigraphic sections, ranging from the Precambrian Vishnu Schist at the base of the Inner Gorge to the Permian Kaibab Limestone at the Rim.
