The park encompasses the caldera of Crater Lake, a remnant of a destroyed volcano, Mount Mazama, and the surrounding hills and forests. The lake is 1,943 feet (592 m) 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.
The lake is 5 by 6 miles (8.0 by 9.7 km) across, with a caldera rim ranging in elevation from 7,000 to 8,000 feet (2,100 to 2,400 m) and an average lake depth of 1,148 feet (350 m).The lake's maximum depth has been measured at 1,949 feet (594 m), which fluctuates slightly as the weather changes.everal species have formed self-sustaining populations. Since 2002, one of the state's regular-issue license plate designs has featured Crater Lake. The commemorative Oregon State Quarter, which was released by the United States Mint in 2005, features an image of Crater Lake on its reverse.
