You comment on the dirt in the bottom. Did you climb down there? The hole looks pretty unstable from your pictures. Is there any air flow in or out of the hole? Without airflow going in or out of the hole I wouldn't expect too much in terms of cave passage.

Looks good to me! Really only one way to find out if it does something. Looks stable from here. :big grin: What kind of limestone do you have under you? Good luck with it.

I'd rather enlarge shaft and provide collapse-arrest. Latter could be braced 4x4 treated wood timbers or
steel culvert pipe diameter up to four feet. Extra expense and work, yes. Safer, yes. Have I done it, yes.

there is air flow from bottom right, a mouse comes out from under that rock on bottom right that's were air flow is, its solid rock all way down about 15ft of lose cold dirt is laying down there, hole is to small in diameter to get in , and for backhoe, need large vacuum or something like to suck out lose dirt
