Animal bones have been discovered in this cave, which have enabled us to learn about the fauna, and thus the different climates of the Quaternary period. Red deer, Asian dogs, wolves and rhinoceros lived during temperate to hot periods, while reindeer, polar foxes and marmots related to cold or glacial periods.
The cave, interestingly, is always constant at 18.5 degrees and that's hot when you are climbing steps, which is what we are about to do tomorrow - we are on our way up and out!
