Crater Lake Overview

Crater Lake is a caldera lake in the U.S. state of Oregon. It is the main feature of Crater Lake National Park and famous for its deep blue color and water clarity. The lake partly fills a nearly 4,000 feet (1,220 m) deep caldera that was formed around 5,677 (± 150) BC by the collapse of the volcano which was later named Mount Mazama. The lake has no inlets or outlets for the water. Rain and snow, generally in the range of 550 inches per year, keeps the water level at a fairly constant level. It is the deepest lake in the United States, and the second deepest in North America (after Great Slave Lake in Canada)

On June 12, 1853, John Wesley Hillman was reportedly the first European American to see what he named "Deep Blue Lake" in Oregon. The lake was later renamed 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 side.
