At 2940m (9678ft) a.s.l the cave known as Abyss of Cenote is located in the heart of the mountain called Conturines Spitze in the Italian Dolomites. It is characterised by a rather strange shape, somewhat like a wine bottle, which is narrow at the top and opens up into a huge chamber at the base. The narrow ‘neck’ of the cave is corked with a huge ice plug that has started to melt in recent years allowing cave explorers to work their way down around its sides, through the middle, and out of the bottom into the rest of the cave, Here, Lars is returning up through the ice plug after a trip underground with the scientists working in the cave. Many different layers can clearly be seen in the ice above his head, with some parts having a lot of detritus and organic material giving the dirty look, whilst other parts are cleaner and white. At the moment, the reason behind the dirty layers versus clean layers in unknown. Scientists are currently working on its interpretation.
