Detroit salt mine

From Wikipedia, the free encyclopedia

The Detroit salt mine is a salt mine located 1,100 ft (340 m) below Detroit, Michigan. The mine opened in 1910 and covers 1,500 acres (610 ha) underground.[1] In the beginning, the leather and food industries were the primary customers. Today, road deicing salt is the primary product.[2]

History[]

Rock salt was discovered in 1895. The Detroit Salt and Manufacturing Company was formed to extract the salt. The company went bankrupt before finishing the shaft down to the salt. A new company was formed and the shaft was completed in 1910.[2] A second larger shaft was completed in 1925. The first shaft was relegated to hauling workers and materials.[2] By the late 1950s, the company operated through both shafts, which are about 1100 feet deep.[3] The mine was closed from 1983 to 1998, when production was restarted to produce road deicing salt.[2] In October 2010, the Detroit Salt Co., LLC, was acquired by the Kissner Group of Canada for an undisclosed price.[4]
