Most of them weren't really found too close to the rail road tracks, a few pieces were, but many were found in the field and along the creek next to the tracks. Best, Joe Kerchner

If you dont have one yet and would like to have an awesome wrong, this is it. Its my opinion that this is some sort of industrial waste or slag as I cant imagine this forming naturally on Earth. Given that a good portion was found close to railroad tracks, it might be interesting to see if there was a lost car (derailed) or something of that nature in the area of the find. I should have more testing results soon, when I get them, I will offer it to everyone.
