Photo by Robbie Shone @shonephoto | Suspended on a thin rope, engulfed in cloud and lost in time, a tiny figure in red is dwarfed by the sheer size on a monumental scale of Cloud Ladder Hall. The beam of light cast by another explorers head torch pierces the fog yet illuminates nothing. This room is so large it has it's own weather system going on. From the central ridge overlooking the cathedral like Cloud Ladder Hall, towering up into the fog, figures add scale to this gigantic cave. High up in the distance, the roof remains unseen to the explorers. However, estimates in it's size show that it must cut through many levels of cave development along the way. This is the fourth largest cave chamber ever found in the world today.
