With a depth of 1,943 feet (592 meters) Crater Lake is the deepest lake in the United States and the seventh deepest in the world. It is surrounded by steep rock walls that rise up to 2,000 feet (600 meters) above the lake's surface.
Crater Lake was formed 7,700 years ago when a massive eruption of Mount Mazama caused the mountain to collapse leaving a steaming caldera. Centuries of rain and snow filled the caldera or volcanic crater creating Crater Lake.
A small volcanic island, Wizard Island, rises 767 feet (234 meters)
above the surface of the lake on it west side. A small crater, 300 feet
(90 meters) across and 90 feet (27 meters) deep, rests on the summit.
Crater Lake was named for this beautiful, symmetrical crater by James
editor of the Oregon Sentinel in Jacksonville, in 1869.
Crater Lake averages about 500,000 visitors per year.
