Crater Lake

Crater Lake (Klamath: Giiwas) is a volcanic crater lake in south-central Oregon in the Western United States. It is the main feature of Crater Lake National Park and is a tourist attraction for its deep blue color and water clarity. The lake partly fills a 2,148-foot-deep (655 m) caldera that was formed around 7,700 (± 150) years ago by the collapse of the volcano Mount Mazama. No rivers flow into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 150 years. With a depth of 1,949 feet (594 m), the lake is the deepest in the United States. In the world, it ranks eleventh for maximum depth, as well as fifth for mean depth. Crater Lake features two small islands. Wizard Island, located near the western shore of the lake, is a cinder cone about 316 acres (128 hectares) in size. Phantom Ship, a natural rock pillar, is located near the southern shore. Since 2002, one of Oregon's regular-issue license-plate design has featured Crater Lake and a one-time plate surcharge is used to support the operation of Crater Lake National Park. The commemorative Oregon State Quarter, which was released by the United States Mint in 2005, features an image of Crater Lake on its reverse. The lake and surrounding park areas offer many recreational activities, including hiking, biking, snowshoeing, fishing, and cross-country skiing, and during the summer, campgrounds and lodges at Crater Lake are open to visitors.
