Which lake contains Wizard Island, a volcanic cinder cone? Crater Lake contains Wizard Island in Oregon.

Wizard Island formed inside the caldera of Mount Mazama, a large volcano that erupted about 7,700 years ago. That enormous eruption emptied part of the volcano's magma chamber and caused the summit to collapse, creating the basin now filled by Crater Lake.

Later eruptions on the caldera floor built several cinder cones. Wizard Island was the highest of them and the only one to rise above the modern lake surface. Its summit reaches about 6,933 feet above sea level, and its own crater is known as the Witches Cauldron.

A common mix-up is to treat Wizard Island as a separate volcanic island or confuse it with another crater-lake feature. It is specifically an island within Crater Lake, part of Crater Lake National Park. Another submerged cone, Merriam Cone, never rises above the water.
