Ice age caves discovered underneath city of Montreal

For years, Mr Le Blanc and Mr Caron, both members of the Quebec Speleological Society, believed there must be another set of caves connected to Saint-Léonard Cavern near Parc Pie XII in the Saint-Léonard neighbourhood of Montreal, but they did not know exactly where.

Then in 2014, the pair got their first inkling o f what might be underneath when dowsing rods - a stick used to search for groundwater - found a small fissure in the ground.

...

So far, they've explored about 150 metres of the passageway, all while doing precise surveying for the city to make sure no homes above ground are affected by the cave.

They are waiting for winter, when the water table gets lower, to explore the rest of the caverns, which they think go on for at least another 50 metres.

"We still have more exploring to do," he said. "For us it's a major discovery, the kind of discovery you make once in a lifetime."

That was back when humans used too many air conditioners and caused global cooling.

I’ve been in a number of caves in my life, and none has had vertical walls and a perpendicular ceiling. I suspect something is amiss with at least the pictures.

[caver]

I agree. It looks like a mined shaft.

You are right - those are mine shafts or something definitely man-made. As for Ice Age, that may be just conjecture on their part, else there were mining operations going on 15,000 years ago - not really a stretch as no one has figured out exactly who mined all the copper in the Michigan UP or where all the copper went.

Ah, now we know where the Egyptians got those rocks for the pyramids.
