Well, Lake Calumet and environs are pretty low. A lot of Steel Slag was used to fill in low marshy areas. The Irony! U.S.S. shutting plants at a time when their by-product could be used to counter alleged lake level rise! ;)

I almost commented earlier today but since you pinged me I will. Yes lots of steel slag. Even down deep under our vegetable garden. 111th and Avenue M on the East Side is where I grew up. Most everyone in the neighborhood worked in the mills. Dad always fished in Lake Calumet from shore. A few times we had so much rain all the sewers backed up and we had water in the basement.
