A crater lake is a lake that forms in Volcanic Caldera s or Crater s after the volcano has been inactive for some time. The best-known crater lake, which bears the same name as the geological feature, is Crater Lake in Oregon state's Mount Mazama . Some crater lakes are acidic, however, some lakes' water remains fresh. Some also have geothermal activity, especially if the volcano is merely dormant rather than extinct. Crater Lake in Crater Lake National Park is isolated from rivers and streams, and therefore has no in or out flow, and hense, no pollution or chemicals. It is fed by melting snow. The extreme depth of Crater Lake (1949 feet), causes the sunlight to refract in the clear water in such a way as to generate a rare deep blue color. Lakes can also fill Crater s formed by Impact Event s. An example is the Bosumtwi Crater in Ghana, Africa. VISUAL
