“It’s just beautiful,” said Luc Le Blanc, who found the network of caverns earlier this year with fellow spelunker Daniel Caron. Now all that was left was the gruelling task of piercing through the ancient limestone walls of the existing cave. “We could then see there was indeed a void and it was bigger than we thought,” said Le Blanc. The walls are perfectly smooth, perfectly vertical and the ceiling is a perfectly horizontal slab,” said Le Blanc. “But it keeps going, so we have no idea where it will end,” said Le Blanc.
