Crater Lake, Oregon, USA
Wizard Island cinder cone, with a symmetrical 90-m-wide crater at its summit, formed above the west floor of Oregon's Crater Lake caldera within a few hundred years of caldera formation.
A lava flow created the peninsula in the foreground on the NW side of the cone, which forms a small island on the west side of Crater Lake.
A submerged dome, 30 m beneath the surface 1 km east of Wizard Island, is the youngest feature of Crater Lake caldera.
