When considering the mean, or average depth of lakes, Crater Lake becomes the deepest lake in the Western Hemisphere and the third-deepest in the world. Crater Lake Institute Director and limnologist Owen Hoffman states that "Crater Lake is the deepest, when compared on the basis of average depth among lakes whose basins are entirely above sea ...
Crater Lake is often referred to as the seventh-deepest lake in the world, but this former listing excludes the approximately 3,000-foot (910 m) depth of subglacial Lake Vostok in Antarctica, which resides under nearly 13,000 feet (4,000 m) of ice, and the recent report of a 2,740-foot (840 m) maximum depth for Lake O'Higgins/San Martin ...
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.
Volcanic crater lake – Lake formed within a volcanic crater; Subglacial mound – Volcano formed when lava erupts beneath a thick glacier or ice sheet; Submarine volcano – Underwater vents or fissures in the Earth's surface from which magma can erupt; Supervolcano – Volcano that has had an eruption with a volcanic explosivity index (VEI) of 8
The name maar comes from a Moselle Franconian dialect word used for the circular lakes of the Daun area of Germany. The word evolved from its first use in German in the modern geological sense in 1819 and is now used in English and in the geological sciences as the term for the explosion crater, even if water from rainfall might always have drained from the crater after the formation event.
Crater lake, a volcanic lake in Oregon. Volcanoes that, though large, are not large enough to be called supervolcanoes, may also form calderas (collapsed crater) in the same way. There may be active or dormant cones inside of the caldera or even a lake, such lakes are called Volcanogenic lakes , or simply, volcanic lakes.
A salt lake, also known as a saline lake or brine lake, is an inland body of water situated in an arid or semiarid region, with no outlet to the sea, containing a high concentration of dissolved neutral salts (principally sodium chloride). Examples include the Great Salt Lake in Utah, and the Dead Sea in southwestern Asia. [36] [52]
