Sebewaing coal mine

The Sebewaing Michigan Coal Mines

The discovery of coal in Sebewaing was made by Russell Brothers; well diggers based in Unionville. By the early 1900’s Sebewaing had three coal mines in operation. The Whittier, Sebewaing Coal Company and the Saginaw Bay Coal Company collectively employed about 100 men. Coal was brought to the surface on small mule driven cars on wooden tracks.

Coal mining was successful for only a few years. It seems that initially, the coal was of high quality however as operations continued it seems that the extracted coal contained so much sulfur it was deemed too explosive to be used as a fuel. Thomas Whitter, a chemist from Saginaw inspected the coal vein and found it an excellent source of pyrite and comparable with the pyrite sources then being imported from Spain. Changes were made to the operation that expanded mining capacity to 400 tons per day. Pyrite ore is an excellent material in which to make sulfur.

Below is a sketch map of the location of the mines in and around Sebewaing.

    1. Unionville curve by the Gateway Gun Club has always been referred asThe coal mine corner. There are tunnels that run for several miles underground in that area. The water is salty in that area, and some say it is because of those coal mines.

      1. This is so interesting for us to learn. Thank you Dianne. We find it something how our next door neighbor has this and we weren’t fully aware. So refreshing to learn new things.

  1. Thanks, Thumbwind – fascinating. I grew up in Sebewaing and knew we had coal mines around the 1900s, but I’ve never seen this photo and didn’t know that much of the story. We’re sharing your post on the “You Know You Are From Sebewaing…” Facebook Page.
