My sensors registered that Crater Lake is filled with the clearest, bluest water I've ever seen. The lake is surrounded by a caldera formed by the collapse of Mount Mazama over 7000 years ago. It's also the deepest lake in the United States and the ninth-deepest in the world. These physical measurements make Crater Lake an incredible sight to behold.
