Today started with a visit to 'Mount Doom' – a tall conical mountain about 1000m from the Von Damm vent site and similar in size and shape. Although no active venting was encountered on Mount Doom, a return trip to the Von Damm site approaching from the East encountered more tube worms and a new site of active venting outside the previously explored area, almost doubling the total extent of venting now known at the site.
