Castle in the Crater
Crater Lake National Park
Klamath Falls, Oregon
Pumice Castle, shaped like the battlements of a castle, when pumice and other lavas welded together at high temperatures. These air-filled deposits were buried and compacted by later lava flows and exposed when Mount Mazama collapsed. A hardened base has kept Pumice Castle intact as softer materials have eroded away.
Tomorrow another adventure begins.
