impressive lavacicle formations. Perhaps this is the most famous feature of the cave, a small pillar w/ a welded rafted block of lava attached. The ceiling height here is relatively low, look to see the old signature from E.L. Hopkins dated October 2, 1892. The brown shiny lava drippings (lava ribs) down the wall give the cave the name, as they are seen throughout the passageway. Parts of the walls are covered in bacteria, which light up bright gold when water droplets cover them.
