Michigan

Michigan is not a cave state, there is only a little limestone and only one single show cave. But Michigan has a long history of iron and copper mining, which continues until today. Beneath those two main resources, gold, silver, gypsum, slate, salt, coal and limestone have also been mined. So there is a wealth of mining museums, show mines and also the possibility to visit a working mine.
