THANK YOU for the measurement. It looks like approximately 4" x 4", which should help us. One end of it looks bent & tapered.
Since it is a fairly large steel item,, is there evidence of a train or railroad track in the area ??
No train tracks. It was found in a feild near Peublo Viejo historic site. The fort built by Columbus in 1492. I got permition to hunt the field but only had a short time and didn't find much.
