Union & Steel Furnace Location
This furnace is quite confusing because it changed names so many times...in 1900 it is listed on the Sanborn maps as the Ironton Furnace....if you look at this same location in other years (and follow the business records) it changes hands multiple times. **Notice the incline tracks on the bottom of the map. They are still visible today just cut off.
