Lava tube cave: Lava Beds National Monument, Medicine Lake Volcano, CA

2012 (approx.)

Detailed Description

The horizontal traces near the floor of the cave wall are remnants of high stands of lava as it drained away during the final stages of lava-flow activity within the tube. The drip structures from the ceiling were formed as the top of the cave remelted and dripped downward due to the high temperatures within the tube system.
