John Hageman said: All joking aside, salt mines collapsing…
John, I thought it was just a good joke when I saw it on the other website. But they also put up this video of a salt mine accident in Louisiana. What happened was way beyond what I ever expected.

I did a little bit of rough calculations to find out what would happen in Lake Erie. The people who monitor the Lakes use the metric system so everything is cubic meters.
Cleveland salt mine production 2 500 000 tons per year, density of salt about 2
That is 1 250 000 cubic meters of volume per year times 60years?
75 000 000 cubic meters total
The Niagara River flow is about 5 000 cubic meters per second. Only half of that or less goes over the falls. The rest is used to generate electricity.
That works out to 250 minutes of Niagara River flow pouring into the mine to fill it.
Less than 1 inch of water level drop in Lake Erie.
Not much water out of the lake overall but judging from the video it would be a huge disaster.
