Mine: Michigan Alkali, Alpena, MI
The Michigan Alkali Company was located along the Detroit River in Detroit, but it was supplied with limestone from this quarry just north of downtown Alpena. This quarry continues to be used today by the cement plant in Alpena. This quarry was served by the Detroit & Mackinac Railway, but most produce was shipped
by lake freighter.
