Lava Beds

Catacomb Cave

Angel I Moreno

Lava Beds National Monument is on the northern part of the Medicine Lake Volcano. The caves here are not the common limestone caves with stalactites and stalagmites all over the place. They are lava tubes in basalt, formed when the outer layer of lava hardens before the lava inside. When the lava inside flows out, a hollow tube is created.
