What makes it unique are the fantastic colors—deep blue in the middle and reds and oranges around the edges. These colors come from tiny microbes that live in the hot, mineral-rich water.
Crater Lake

Over 7,700 years ago, Mount Mazama collapsed, forming a breathtaking natural wonder known as Crater Lake. It is the deepest lake in the United States, plunging to depths of nearly 1,950 feet. The lake’s purity is maintained by the absence of inlets or tributaries, relying solely on rainfall and snowmelt.
