Underground Tunnels in Michigan

I was born in Detroit and grew up about 45 minutes from the city. As a kid, I always heard stories about the underground salt mines in Detroit. I never explored them, but have heard stories of people going into those underground tunnels.

In grade school, we were learning about the history of Michigan. We learned about the iron and copper mines in the Upper Peninsula. Iron ore was discovered in 1844, and copper was mined by Native Americans as early as 3000 B.C., but settlers began mining in the mid-1800s. There are tunnels all over the Upper Peninsula because of it.

Secret tunnels are in Kalamazoo, Albion, Detroit, the Upper Peninsula, and Grand Rapids.

According to FOX 17, 85 feet under the City of Grand Rapids, a maze of secret tunnels dates back to the 1800s when gypsum was mined in Michigan.

A poster on Reddit showed a newspaper clipping that provided a map of the underground tunnels in Grand Rapids. Below is what people had to say about it on the Grand Rapids Reddit page.

It's crazy to post a map of underground tunnels in a newspaper for every kid to see and figure out how to get down there.

This poster may not have seen the article that FOX 17 posted a couple of years ago that talks about how 20% of the mine operates as an underground fridge that stores food and alcohol
