Crater Lake (Klamath: Giiwas) [2] 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 is 1,949 feet (594 m) deep at its deepest point, [4] which makes it the deepest lake in the United States, the second-deepest in North America and the tenth-deepest in the world. [4]
The deepest area is oceanic rather than continental crust. However, it is generally regarded by geographers as a large endorheic salt lake. Of these registered lakes; 10 have a deepest point above the sea level. These are: Issyk-Kul, Crater Lake, Quesnel, Sarez, Toba, Tahoe, Kivu, Nahuel Huapi, Van and Poso.
Crater Lake actually started as a mountain, Mount Mazama. A volcanic eruption roughly 7,700 years ago caused the mountain to collapse inward over time, forming a volcanic crater, the park says.
Crater Lake is 1,943 feet (592 m) deep, the deepest freshwater body in the U.S. and the second deepest in North America after Great Slave Lake in Canada. Mount Mazama formed as a group of overlapping volcanic edifices such as shield volcanoes and small composite cones , becoming active intermittently until its climactic eruption 7,700 years ago.
Wizard Island was created after Mount Mazama, a large complex volcano, erupted violently approximately 7,700 years ago, forming its caldera which now contains Crater Lake. Following the cataclysmic caldera-forming eruption, which left a hole about 4,000 feet (1,200 m) deep where the mountain had once stood, a series of smaller eruptions over ...
Lake Erie is the shallowest of the Great Lakes but bests its cousins in several other ways. Find out more about all the Great Lakes.
Mount Scott is a small stratovolcano and a so-called parasitic cone on the southeast flank of Crater Lake in southern Oregon. [4] [5] It is approximately 420,000 years old. [3] Its summit is the highest point within Crater Lake National Park, and the tenth highest peak in the Oregon Cascades. [6]
