Found this on the banks of a large cypress pond/swamp in the Florida panhandle. It is not metal! Any help in identifying what it is would be very much appreciated.
Could the so-called "Money Pit" really be nothing but a man-made reservoir to hold some of the water from the Swamp when the Swamps plug is pulled?? And then to refill the Swamp using gravity AFTER those who created this ingenious system were done doing whatever they were doing in the Swamp...
