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 level. The average depths of Lakes Baikal and Tanganyika are deeper than Crater Lake; however, both have basins that extend below sea level." [19] [21]
Crater Lake is called Giiwas in the Klamath language. [7] Steel had helped map Crater Lake in 1886 with Clarence Dutton of the United States Geological Survey. The conservation movement in the United States was gaining traction, so Steel's efforts to preserve the Mazama area were achieved on two scales, first with the creation of the local ...
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.
The caldera rim reaches a maximum elevation of 6,716 feet (2,047 m). In 1975 the surface of the crater lake was at an elevation of about 4,220 feet (1,286 m), and the estimated elevation of the caldera floor is about 3,400 ft (1,040 m). The mountain is located in Kodiak Island Borough, very close to its border with Lake and Peninsula Borough ...
A volcanogenic lake is a lake formed as a result of volcanic activity. [1] They are generally a body of water inside an inactive volcanic crater ( crater lakes ) but can also be large volumes of molten lava within an active volcanic crater ( lava lakes ) and waterbodies constrained by lava flows, pyroclastic flows or lahars in valley systems.

Construction of the observation station began in the fall of 1930. During construction, Sager spent hours in a rowboat on the lake, ensuring the building blended perfectly into the caldera cliff. As a result, the building provides a spectacular view of Crater Lake and surrounding caldera and mountains, but is virtually invisible from the lake ...
Located at an altitude of 1,197 m [ a ], the lake was formed by phreatomagmatism, in other words it is a maar.Generally circular in shape with a diameter of 700 to 800 m and an area of 44 ha, it has an average depth of 29.5m and a maximum depth of 92m , making it the deepest in Auvergne [3] ( i.e. a volume of approximately 13 million m 3 of water).
