Wizard Island is a volcanic cinder cone which forms an island at the west end of Crater Lake in Crater Lake National Park, Oregon.
The top of the island reaches 6,933 feet (2,113 m) above sea level, about 755 feet (230 m) above the average surface of the lake. The cone is capped by a volcanic crater about 500 feet (150 m) wide and 100 feet (30 m) deep. The crater was named the "Witches Cauldron" by Will G. Steel in 1885, who also gave Wizard Island its name at the same time.
