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 .
Satellite view of Crater Lake. Volcanic activity in this area is fed by subduction off the coast of Oregon as the Juan de Fuca Plate slips below the North American Plate (see plate tectonics). Heat and compression generated by this movement has created a mountain chain topped by a series of volcanoes, which together are called the Cascade Range ...
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 ]
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.
Mazama and Crater Lake form part of the Mazama reach (section) of the Oregon Cascades, which stretches for 25 miles (40 km) from Timber Crater to the Big Bunchgrass shield volcano. This includes 175 Quaternary volcanic vents within a belt that ranges from 16 to 19 miles (25 to 30 km) in width, which has a high vent density with many shields and ...
It is located on the north rim of Crater Lake in Crater Lake National Park. Topographic relief is significant as the summit rises 1,870 feet above the lake in 0.28 mile. The rock pillar was named after Llao, a Native American god. [4] The landform's toponym was officially adopted in 1897 by the United States Board on Geographic Names. [3]
Landsat image of Lake Toba, Indonesia, the largest volcanic crater lake in the world. A well-known crater lake, which bears the same name as the geological feature, is Crater Lake in Oregon. It is located in the caldera of Mount Mazama. It is the deepest lake in the United States with a depth of 594 m (1,949 ft).
Mount Mazama's eruption timeline, an example of caldera formation. A caldera (/ k ɔː l ˈ d ɛr ə, k æ l-/ [1] kawl-DERR-ə, kal-) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcanic eruption.
