Explorers have just discovered a new underground passage, complete with stalactites and a lake, all buried beneath the city of Montreal — and they don't know where it ends yet.

Until a couple of months ago, no one had ever set foot inside.

CBC crews were among the first people who had the chance to explore the cathedral-like chamber, which was formed more than 15,000 years ago during the ice age.

Cavers Luc Le Blanc and his friend Daniel Caron couldn’t believe their eyes when they knocked through limestone and discovered this massive chamber beneath Montreal. (Submitted by Société québécoise de spéléologie)

The spectacular find is connected to Montreal's Saint-Léonard Cavern, which lies underneath Parc Pie XII, not far from Highway 40.
