Here is Wizard Island, a small volcanic island in Crater Lake. "Following
the collapse of Mount Mazama, lava poured into the caldera even as the
lake began to rise. Today, a small volcanic island, Wizard Island, appears
on the west side of the lake. This cinder cone rises 760 feet (233 meters)
above the lake and is surrounded by black volcanic lava blocks. A small
crater, 300 feet (90 meters) across and 90 feet (27 meters) deep, rests
on the summit. The crater is filled by snow during the winter months,
but remains dry during the summer. " |
