Many stories and traditions around the world speak that beneath the surface there would be a network of tunnels that would connect various important points of the planet. Is this more than just a legend told from generation to generation?
Now, a team of Canadian speleologists have managed to discover an extensive cave system under the city of Montreal, Canada, dating from the last Ice Age.
Daniel Caron and Luc Le Blanc, researchers from the Speleological Society of Quebec, inspected the cave of Saint Leonard, whose underground spaces were already discovered in 1812. However, only in the middle of last October they managed to access a “labyrinth” of tunnels previously unknown; according to the National Geographic magazine .
In this underground space with just over 200 meters wide and about six meters high, the limestone walls are completely smooth and the roof “is perfectly horizontal,” said Le Blanc.
“They have dug sewers and made basements, but nobody had ever seen them,” La Blanc said of the cave network.
Caron and Le Blanc decided to explore their hunch in 2014, when they began speculating in the caves of St. Léonard in search of new passages.
Le Blanc, armed with a new radiolocation team, and Caron, using a divining rod, looked for gaps or water signs on the other side of the cave walls. In 2015, they had found a small narrow opening in the back of a cave. Using a small camera, speleologist François Gelinas was able to cross the opening, where they saw a large room just behind the wall.
Although they were anxious to cross the wall, they could not pass through it until almost two years later. The walls of the cave at St. Leonard are made of solid limestone, and the opening of a step requires industrial strength exercises.
The scientists also found stalagmites and stalactites, which the site would have formed around 10,000 years ago as glaciers receded and “separated” the rocks.
To corroborate this theory, Luc Le Blanc detailed that the crashes on one side “fit perfectly in a hole” that is on the opposite wall and described the parallel faces of the walls as pieces of a puzzle.
According to Caron, the farthest reaches of the cave finally reach the water table in Montreal, and an aquifer below.
So far, Caron and Le Blanc have been able to estimate that the 10-foot-wide passage extends approximately 700 feet. Unfortunately, their exploration has been stopped by the water being poured into the confines of the cave, but they plan to return in February after the water recedes.
