lava dripping to ocean

I was visiting the Big Island of Hawaii with some friends and family, and my brother convinced the group to take a lava tour by boat. I always kind of balk a little bit at overtly touristy stuff like that, but I think everyone was a pretty shocked when we got our first look at the Kalapana Lava Flow after about a half hour boat trip down the coast. It’s such an awesome, phantasmagorical sight and, since they actually get surprisingly close to the spots where the rivers of lava meet the ocean and throw up sulfurous steam clouds, also a pretty visceral sensory experience.
