One of the largest salt mines in the world exists under Lake Erie
cr1895: Would highly recommend the book "Salt" by Mark Kurlansky. I never realized how influential salt was to the course of human history.
joecool1029: The largest salt mine in the world is under Lake Huron: https://www.compassminerals.com/who-we-are/locations/goderic...
SilverElfin: What happens when they run out of salt? All the salt they put on the roads must end up back in the lakes but not in a way that is as easy to extract, right?
therealdrag0: My initial reaction was fear.But then I wondered if modern mining engineering is a solved problem? In that they mostly know how to make safe tunnels?Then I looked up how deep Erie is and it’s pretty shallow, with an average depth of 62 ft!
vasco: Salt mines in particular are of the safest kind in the whole world, they are super stable. It's a self supporting rock with enough plasticity that the whole thing doesn't crumble down.If you ever have privileged info of a huge earthquake happening, going into a salt mine is probably not the worst idea.Plus it rehabilitates your lungs to be in a salt mine for a long time.
