Thanks to those of you who have sent information concerning the various coal mines and other information on the subject. I appreciate all of it and will try to follow-up on the books referred to. I have copies of the U.S. Geological Survey Maps for much of Jefferson county which were printed in 1960. I haven't checked to see if there are more recent additions. It is interesting, and somewhat tragic, seeing the amount of land that has been strip-mined in the area. I wonder if anyone knows if there are any of the old underground mines that have been "worked out" still in existence. I can remember as a child visiting one in particular. It appears that where many of these mines were located were within the areas that were strip-mined. I know of some mines in other areas that have been preserved as historic sites, but to my knowledge there are none in Jefferson or Harrison Counties, OH. Any information about mine "sites" that are still in existence? Ed Durbin
