Havasu Falls, Grand Canyon, Supai, Arizona, United States

Havasu Falls (Havasupai: Havasuw Hagjahgeevma) is a waterfall in the Grand Canyon located 1½ miles (2.4 km) from Supai, Arizona, USA. It is arguably the most famous and most visited of all the falls on Havasu Creek and consists of one main chute that drops over a 90-foot (27 m) to 100-foot (30 m) vertical cliff into a large pool. Due to the high mineral content of the water, the configuration of the falls is ever-changing and sometimes breaks into two separate chutes of water.
The falls are known for their natural pools, created by mineralization, although the configuration of the falls and the pools are damaged or destroyed repeatedly by large floods that wash through the area. A small man-made dam was once constructed to help restore the pools and to preserve what is left.
High calcium carbonate concentration in the water creates the vivid blue-green color and forms the natural travertine dams that occur in various places near the falls.
There are many picnic tables on the opposite side of the creek, and it is easy to cross over by following the edges of the pools. It is possible to swim behind the falls and enter a small rock shelter behind it.
