Crater Lake National Park
Crater Lake has long attracted the wonder and admiration of people from all over the world. Its depth of 1,943 feet (592 meters) makes it the deepest lake in the United States, and the seventh deepest in the world. Its fresh water is some of the clearest found anywhere in the world. The interaction of people with this place is traceable at least as far back as the eruption of Mount Mazama 7,000 years ago.
Located in Southern Oregon on the crest of the Cascade Mountain range, 100 miles (160 km) east of the Pacific Ocean, the lake lies inside a caldera, or volcanic basin, created when the 12,000 foot (3,660 meter) high Mount Mazama collapsed following a large eruption.
Generous amounts of winter snow, averaging 533 inches (1,354 cm) per year, supply the lake with water. There are no inlets or outlets to the lake; evaporation and seepage prevent the lake from becoming any deeper.
