Crater Lake
Summary
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 famous for its deep blue color and water clarity. The lake partly fills a 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 250 years. With a depth of , the lake is the deepest in the United States. In the world, it ranks ninth for maximum depth, as well as third for mean (average) 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 ha) in size. Phantom Ship, a natural rock pillar, is located near the southern shore.
Since 2002, one of Oregon's regular-issue license-plate designs 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 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.
Crater Lake is in Klamath County, around northwest of the county seat of Klamath Falls, and about northeast of the city of Medford.
A Native American connection with this area has been traced back to before the eruption of Mount Mazama. Archaeologists have found sandals and other artifacts buried under layers of ash, dust, and pumice that antedate the eruption roughly 7,700 years ago. Crater Lake remains significant to the Klamath tribes today. The Klamath name for the lake is Giiwas.
In June 1853, Isaac Skeeter, John Wesley Hillman, and another man were the first non-Native Americans to report sighting the lake, while on a mining trip; Skeeter named it "Deep Blue Lake," inspired by Hillman's description of the site.
