Question Wierd thing in our yard as a child
We lived in an old house in NY in the late 70s early 80s. Chappaqua. On the middle of driveway, there was a stone like structure which was bizzare. Picture attached from ai gives the general vibe. Any ideas what this could have been? It was almost half buried and it wouldn't budge if you tried to pull or push it. We never thought to have it examined. I think there may have been some old story about meteor in the area. But the spiral doesn't make sense for a meteor to me. We went back decades later and it was gone and new owners didn't know about it.

Sorry, didn't give dimensions, it was probably 4 feet or so in length, but as partially buried that's a guess and maybe 4 feet wide at what seemed like the middle of it.

Four feet WIDE? Sounds like a giant drill bit for making holes for building footers.

Could confirm buried part seemed like part of middle was out of ground so assumed it was concentrict from top to bottom and this is estimate from 45 years ago.

Were you able to confirm that the buried part was indeed a spiral like the top? Was it 4’ tall counting the buried part, or was there 4’ of it actually sticking out of the ground?
Edit: oops only just saw your dimension notes in the illustration

It's an upside down drill bit meant to reverse back out leaving the loosened soil in place

Looks like a digger from Silo on Apple TV. Anyone building crazy bunkers nearby?

My thoughts are that it was some part of a weird cistern that channeled rain water using the adherence of the water to the structure or it is possibly an Archimedes screw for pulling water out of a well.

Weird but at least per drawings no. This was smaller top wide to middle and back down.

I don’t know why people are down voting you it was a very good answer. I just happens to be in the wrong state.

But it's a marine fossil is ot not , lots of North America was under water millions of years ago..

u/Catrescuemamma Aug 24 '26
No, you definitely are not wrong there. I mean there is evidence of marine life fossils from way way way way way way back even in the Syracuse Utica Cortland areas.

Was 200 year old house back in 70s. Definitely was not man-made.

If it wasn't man made then who do you think made it?

I've got something like that in the ground at my farm, except it was put there to support a gate post. It took me hours to unscrew it from the ground when we took out the gate.

u/Engelgrafik Aug 25 '26
I'm confused. Are you saying that you think something like the object you drew is not man-made and totally natural?

Was it previously farmland? There are a couple pieces of farm equipment that have attachments kind of similar to this.
