The Grand Canyon is a steep-sided canyon carved by the Colorado
River in the United States in the state of Arizona. It is largely
contained within the Grand Canyon National Park, one of the first
national parks in the United States.
The Grand Canyon is 277 miles
(446 km) long, up to 18 miles (29 km) wide and attains a depth of over a
mile (6,000 feet / 1,800 metres). Nearly two billion years of the
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. While the specific geologic
processes and timing that formed the Grand Canyon are the subject of
debate by geologists, recent evidence suggests the Colorado River
established its course through the canyon at least 17 million years ago.
Since that time, the Colorado River continued to erode and form the
canyon to its present-day configuration.
