National Park Service National Park

Crater Lake became a national park on May 22, 1902, the fifth national park in the United States. The summit of Mount Mazama collapsed about 7,700 years ago, leaving a caldera that filled with snowmelt to a depth of 1,943 feet, making it the deepest lake in the United States.
