    1. Yes indeed. Here is an interactive map of major salt deposits and production facilities in North America, including the Great Lakes area:

  2. This image depicts a massive underground chamber within a German rock salt mine.

    The high-purity salt is extracted from depths of approximately 500 to 550 meters (1,640 to 1,800 feet).

    The vast scale of the excavation relies on leaving large salt pillars behind to support the ceiling structure.

  4. Long as the mining equipment remains down in the salt it has no corrosion, up on the surface it instantly rusts deep and fast, except cast iron components, they stay clean, all the steel alloy is junk in a week.

  5. How fast can I move in my RV, and enough food, water, fuel, and books to last through a volcanic winter or a meteor strike?

  6. Sadly, the scum that are destroying this planet have safe places like this to hide from what they will unleash on the rest of us.
