🔎 UNIDENTIFIED What is in this solid rock cave?

[Tcar]

What is this ? Found in cave through an opening I got these pics with an endoscope camera, around 12-14 ft deep .

Is that vertical or horizontal the way you are going in.

Kind of looks like a heavy duty trap. Pictures aren’t the greatest though. Maybe a creature got trapped and retreated to the cave.

Doesn't look like any trap I've ever seen. No idea what it is, however.

I’m going in vertical at an angle then it turns horizontal,I see some type of old tools or something ? I don’t think in anyway this is natural or an animal . There are carvings and (tools ? )In there.
When the camera gets in there I don’t know up from down but I think a human was in there at one point . There are man made items I’ve never seen in there . What kind of rock is this anyone know ?

Without being there looks like limestone I was thinking vertical throw a big magnet on a rope down there.

I’ve had a small magnet on the endoscope with no luck , there’s another area almost like it that is 600’ away that is almost exactly like it and that tunnel I can see 30’ or so and nothing man made other than chisel marks in stone and what appear to be chunks of ore maybe from 5 pd to small ground chunks 1/2” by 1/2” I’ll post a few of those if wanted

The 4th pic is an old mushroom type musket ball I found 3’ deep close to this area
