Caving in lava tubes

Our adventures included an outing down into one of the magma tunnels formed during a volcanic eruption.  The cave is a 315m tube that lava travelled through.  Inside the temperature is very temperate; it stays the same year round.  The only life inside the cave is a sparkling bacteria (depending on the strain it appears to be a shimmering silver or gold).  I haven’t done much caving, and we spent some time in complete darkness.  It is amazing…your eyes play tricks on you, never really adjusting.  You think you can see light at the periphery of your vision, but can never find it.  Waving your hand in front of your face you can’t see a thing, not even sense the movement.
