The Wizard Island cone formed while the lake was still filling the Crater Lake caldera. The cone grew near the western structural margin of the caldera on top of a broader central platform of lava flows, and the visible portion represents about 2% of post-caldera eruptive products, the rest of which are below the lake surface.
