Wizard Island - Prominent Geological Features of Crater Lake National Park

 

Wizard Island consists of a symmetrical cinder cone almost completely encircled by dark, rugged flows of lava. The summit of the cone rises 763 feet above the the lake, and the area of the cone and lavas exposed above water approximates a square mile. Were it not for the sparse covering of trees, one might suppose that the eruptions had only lately ceased, so fresh is the appearance of both the cone and the flows.
