Sunset at Sentinel Rock over Crater Lake in Oregon.
Crater Lake is located in south-central Oregon in the western United States. It is famous for its deep blue color and water clarity. It was formed around 7,700 years ago by the collapse of the volcano Mount Mazama. There are no rivers flowing into or out of the lake; water levels are maintained by rain and snowfall. It is the deepest lake in the U.S. at 1,949 feet (594 m). (restated from Wikipedia)
