Carving through 277 miles (446 km) of Arizona, U.S.A, and up to a mile (1.6 km) deep in places, the Grand Canyon exposes millions of years of geological history in layers and layers of colorful rocks. The canyon is proof of the power of water over stone. The raging waters of the Colorado River (along with other forces) carved the canyon over millions of years – a process known as erosion.
The Grand Canyon pink rattlesnake is the most common snake in the park, startling hikers as it suns itself on rocks and sandy trails, searching for lizards to eat. Strong geologic evidence suggests the Colorado River broke out of the west end of the Grand Canyon about five million years ago, and no sooner.
