the lake is deep at its deepest point, which makes it the deepest lake in the united states, the second-deepest in north america and the ninth-deepest in the world. crater lake is often referred to as the seventh-deepest lake in the world, but this former listing excludes the approximately depth of subglacial lake vostok in antarctica, which resides under nearly of ice, and the recent report of a maximum depth for lake o'higgins/san martin, located on the border of chile and argentina. however, when comparing its average depth of to the average depth of other deep lakes, crater lake becomes the deepest in the western hemisphere and the third-deepest in the world. the impressive average depth of this volcanic lake is due to the nearly symmetrical caldera formed 7,700 years ago during the violent climactic eruptions and subsequent collapse of mount mazama and the relatively moist climate that is typical of the crest of the cascade range.
