Waterfall inside the Grand Canyon (4 pictures)

Located near Supai and within the Havasupai Indian Reservation in Grand Canyon National Park is Havasu Falls; a picturesque, hidden gem featuring a main chute that drops nearly 100 ft (30 m) over a vertical cliff into a large pool of blue-green water.

Calcium carbonate and magnesium occur naturally in the waters of Havasu Creek. The pools and natural dams form when the calcium carbonate precipitates out of the water and deposits onto the rocks and branches, building up over time. Havasu Falls and Havasu Creek get their blue color from the magnesium in the water. As the pools deepen and the calcium carbonate is slowly released from the water, the bluer the water appears as the relative magnesium content increases. And since the creek originates from a spring, the water rarely deviates from 70 degrees Fahrenheit (21.1 C) year round.
