More than likely, it is a cistern used to water the orchard. Paul
Yea I think the rod idea might be a good way to start. As long as your soil is soft enough (I don't mean frozen or the frost line)... I mean soft enough. In MI. you could push a shovel into the soil and pull out a full shovel full so probing was easy. But here in TN. I'd bend the rod in two after the first 1/2" (there's no such thing as shoveling here). If the soil is soft... maybe make the probe 4-5 ft. because you'll be pushing it a lot it appears horizontally. Grind tip to point and spot weld a handle to other end. Shouldn't cost much at all (so I say). Maybe mark the rod at 6" increments with magic marker or paint with each foot its own color or just count and map.
Ok.... gotta go get more coffee and fix breakfast now. You take day off work and get to probing... WE ALL WANNA KNOW!!!!!!!!! That's all we want for Christmas... well some of us... maybe? Later, Brad

I don't think you are making excuses I would be thinking about that site all day and wanting to get out the but the reality is it's not like we all live in a warm climate this time of year. We got another 6 inches of snow here overnight and from what I've read here it isn't easy to get to and you can't take a 4x4 to the site to haul gear you are going to need as well as warm up in and this thread is nothing like those other threads where someone starts one and we never hear anything again you have been keeping us updated. Hey you never know you might find a jar full of 2 dollar bills in there and only show us one of them lol ( some people might remember that thread form earlier this year). If it warms up and you can pack all the stuff ya need to to the site then you can let us all know what's in there. Keep us updated and here is to hoping you find something amazing in whatever that thing is.
I'd like to see close up of iron sticking out and close up of a piece of the cement. Concrete- not that old, Mortar can be. Tabby - old. Any military training camp in area ? WW1 WW2 looks bunkerish to me. I hunted Camp Wheeler in GA and there were a lot of old bunkers there. I stopped after finding a live Howitzer shell.
It's the highest point in that area, but I don't see how you'd get water up there:

If it is a cistern or water related sure looks like it would be a great place for a wind mill. That might explain a power source.
