In the modern age, we presume that most places on land have already been explored and mapped out, with little room for new terrestrial discoveries.
But back in October, two amateur explorers disproved this assumption with their incredible find. In 2014, Daniel Caron and Luc Le Blanc were making their way through the mapped sections of the St. Léonard Cavern underneath Montréal‘s Pie-XII Park when they came across a small fissure in the back of one cavern. They’d long suspected that there was another set of caves somewhere in there, so they pushed a camera through the crack. It gave a look into another chamber — the beginning of a previously undetected system of caverns and tunnels that were formed during the last ice age.
