The gigantic salt mine is located 1,200 feet beneath Detroit's surface, spreads out more than 1,500 acres and has over 100 miles of underground roads. The mineshaft opening is located at 12841 Sanders Street in Detroit, Michigan.
Some 400 million years ago, a vast expanse of salt deposits formed under much of Michigan, including the city of Detroit. Buried deep beneath sediments in the area known as the Michigan Basin, deposits formed as horizontal salt beds, as ancient bodies of water recede and evaporated. The basin was an arid area of Michigan’s lower peninsula separated from the ocean by a natural bar of land. As the basin continued to sink lower into the earth, salt-laden ocean water repeatedly poured into the depression, where it gradually evaporated, forming miles of salt beds.
Since its earliest days, the mine’s underground city of salt has held the fascination of many and has evolved into a modern day engineering marvel.
