Thanks, there, Seldom.
That is what I was thinking. But, in this particular POI I actually found remnants of an old structure. It is listed as an 1850's era forge. The little I could find on a Google search listed it as a Calatan bloomery. Was quite tickled when we closed in. The poi was only about 80 feet away from the actual foundation we found. Was talking to a local. He was aware of the structure, but did not know what it was.
I called an area museum (that specializes in early iron works) to find more info on it and they'd never heard of it. Found that odd.
