Crater Lake - USA

Crater Lake is a caldera lake in the western United States, located in south-central Oregon. It is famous for its deep blue color and water clarity. The lake partly fills a nearly 2,148-foot deep caldera that 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. Crater Lake is also known for the “Old Man of the Lake”.
