Montreal unveils 15,000 years hidden chambers

CANADA:  15,000-year-old caves were discovered only 10 meters below the streets and parks of Montreal neighbourhood.   

The network of caves  had been discovered  by a pair of amateur  explorers in October.

Two excavators cladding drill machines and hammer dug out the October discovery.

They drilled and hammered through the ancient limestone walls of an existing cave to reveal the vast chamber beyond.

One of the  excavators, Daniel Caron, said it was the discovery of a lifetime  for him, adding that  the dream of every caver is to find a place no one has ever gone before.
