Crater Lake

With a violent volcanic past, the caldera lake in the Crater Lake National Park, Oregon, is a place of immeasurable beauty. Surrounding cliffs of up to two thousand feet high, two small islands and spectacular blue water, make this "outdoor laboratory" the perfect place for photographers.

Crater lake is the deepest lake in the United States with a maximum depth of 1949 feet. It may also have one of the purest water, in North America, (in terms of absence of pollutants) thanks to the generous amounts of winter snow that supplies it with water.
It was created when Mount Mazama (12,000 feet high) collapsed 7,700 years ago following a large eruption, but the legend has more details. The Klamath Indian tribe talks about a raging war between Llao, the spirit of the Below-World who lived in Mount Mazama, and Skell the spirit of the Above-World.
Llao felt in love with Loha, daughter of the Klamath Indian chief, but got rejected and decided to punish humans with the curse of fire. Skell came in to help and after a long battle he managed to defeat Llao, whom he imprisoned deep down into the Under-World, collapsing the top of the Mount Mazama over. At last he wanted peace and decided to cover the pit with magnificent blue water.
