I found some old fiberglass tanks half-buried in an old clay pit in the pine barrens of South Jersey (where all the weird stuff is or happens)! These cylindrical fiberglass tubes are located in an old clay pit that was used by the Atlantic Brick manufacturing Company from the 1930s to the 1950s. These tubes are NOT from that time period, since they did not use fiberglass back then. My question is, of course, what were they used for, and why would someone half-burry them in an out-of-the-way location in the woods? There are several of these "stacked" around the area and have been purposely "half-buried" in clay. The area is not easily accessible by truck or vehicle, only by foot or four-wheelers and dirt bikes today. I'd love to hear others' opinions as to what these were for and WHY anyone would go through the trouble of hauling them out into the woods!
