 We're on we're in the rainforest on the side of Kilauea and behind me is a lava tube. A great lava flow came through here in the past. The top freezes first, the sides freeze, the inside glowing hot lava comes flowing out and it drains. And you go inside and there'll be stalactites that are little drips that were falling off the ceiling when they froze. And this is the way a lot of the lava gets to the coast is that the top will freeze and the insides will go sporting on out to the sea. And so it's a really interesting place, a very different kind of cave.
