Crater Lake

An astronaut aboard the International Space Station captured this image of Crater Lake in southwest Oregon. The lake formed inside a volcanic crater, known as a caldera. Approximately 6,000 to 8,000 years ago, the Mount Mazama volcano exploded and collapsed, leaving behind a crater several miles wide. At a depth of about 2000 feet (600 meters), Crater Lake is the deepest lake in the United States and ninth deepest in the world. 

Wizard Island (red arrow) is a cinder cone formed by an eruption within the caldera.
