A lot of that stuff has been buried. When we bought our 60 acre place in the woods, it had been logged off in the early 1900s for a RR line the bulldozer turned up a lot of metal axe heads horse shoes and the like putting in our driveway. We figured out where the old logging road and several camp locations were, so I took my metal detector down it and found all sorts of buried goodies wagon parts, tools saw blades etc.
