A River Cuts Through Time
The Grand Canyon is a dramatic record of geological history. The Colorado River and erosion exposed layers of rock that reveal an immense span of Earth’s past.
More Than a View
The canyon has long been important to Indigenous peoples and later became a destination for explorers, scientists and tourists. Its scale challenged early visitors and helped fuel the growth of tourism in northern Arizona.
A Symbol of Arizona
Today the Grand Canyon is one of Arizona’s defining landmarks and one of the best-known natural landscapes in the world. Its story combines geology, culture, conservation and tourism.
