Drip Stalagmite

As a lava tube cools down, gasses within the walls expand and extrude liquid material, (lava), into the cave passage. This material can accumulate on the floor of the lava tube to form drip stalagmites, pictured above, or drip from the ceiling to form long, tubular stalactites. Native Guide Hawaii, offers several tours that feature lava tube exploration. Photo: Warren Costa
