The wizard island was formed some time after the cataclysmic eruption which actually formed the caldera underneath it. The island is a remnant of Mt. Mazama. It was first formed by the buildup of hot cinders, which were ejected from the floor of the caldera some around when Mt. Mazama collapsed. It is believed that it first appeared about 7000 years ago. Wizard Island is on top of a platform made of Andesite lava. Some parts of the island were formed from eruptions underwater. The cone shape above the volcano was created as airborne material, ejected by the erupting vent, fell back onto the cone in a symmetrical pattern. The cone rests on a platform of andesite. The island is currently active.
