Never ran across anything like that, could be anything from an old smokehouse/root celler to a burial mound.
I would probably see if I could get a small opening near the cap if possible. It might be completely filled in.
If you know anyone with a snake/drain cam that might be a good route to not disturb anything until you know what it is if you find an opening.
Sorry for not updating sooner.Any updates?
Sounds like its just a dumpload of cement now
i agreeI think that you have found yourself an old cistern. But, it could be full of good old bottles. JMO The ones we have around here are about twenty feet deep so be careful and good luck. BTW, Great thread to follow.![]()
