Crater Lake is one of the most beautiful places we have ever been! It's a volcanic caldera that was formed about 150 years ago by the collapse of Mount Mazama. All of the water in this lake is from rain and snow, and its the deepest lake in the United States at about 2,000 feet deep!
Due to several unique factors, mainly that the lake is cut off from all other water sources, the water in Crater Lake is extremely pure and clear.
It's quite spectacular to see what that clear and blue. Chrissy even jumped in from a rock cliff and went for a swim!
