Wow! This looks like a site I found recently in Osceola County where I live. It appears to have been blown to smithereens and there are chunks of broken iron and rubble everywhere. I'm going to go back and take some pictures and measurements for comparison. All that's left is the footings and when I first detected it, I thought the only thing this place could have been was a still. I also found chunks of coal which was probably the fuel for the boiler. We haven't had coal burning stoves here for years and years. I'll post again when I get the pics.
