The Detroit Salt Mines

In 1895, a huge deposit of rock salt was discovered beneath the city of Detroit, Michigan.

For over a century, workers have tunneled more than one thousand feet down and carved out a network of chambers covering more than five thousand acres. The vast excavation stretches all the way under the city, including downtown.

The mine is still active today, owned and operated by the Detroit Salt Company. Most of the salt harvested is sold as halite, rock salt used to de-ice streets during the winter.


The Detroit Salt Company is not the only organization tunneling under Detroit. A short distance from their salt mine, the Super-Numerical Overachievers Worldwide have carved out their own headquarters in the salty earth.

These math-minded criminals have created a huge subterranean dome where they can meet, exchange formulas, and practice making copies of valuable treasures.

The SNOW built their headquarters close to the salt mine so they can park their phony salt trucks without attracting attention. So far, no one has taken a closer look at the trucks. If they had, they would have found that the trucks around the museums have no salt inside them. They are filled instead with statues, artwork, and jewels—real ones coming out of the museums, and fake ones going in.
