Crater Lake National Park is located in Oregon.

Crater Lake National Park, situated in southern Oregon, is famous for its stunning blue waters and deep caldera, formed by the collapse of a volcanic eruption about 7,700 years ago. It is the deepest lake in the U.S. and one of the clearest in the world, with a depth of 1,949 feet. The park offers scenic views, hiking trails, and opportunities for boat tours. Mount Mazama, which created the lake, remains an active volcano, though it is dormant. The park attracts visitors for its natural beauty, wildlife, and unique geological features.
