“The cave was completely disturbed,” said Clottes, 78. “In 1947 alone, they dug out 600 cubic metres of sediment to make an entrance and concrete path and installed lighting for the public.”
Six hundred cubic metres (22,000 cubic feet) is the equivalent to about eight 12-metre (40 foot) shipping containers.
“No prior study was done, and it completely changed the cave’s micro-climate,” sighed Clottes. “We altered its balance.”
