Carlsbad Caverns in New Mexico most likely. They are probably the largest carbonate caves in the US. These sort of caves form in two stages. First the cave or hole is formed when the formation is below the groundwater table. Groundwater dissolves the rock making the hole. Later as the cave dries out when the groundwater table falls (Carlsbad Cavern were actually lifted up out of the groundwater due to tectonics) the drip and flowstones form. Best known of such formations are stalagtites and stalagmites. The stalagtites hang from the ceiling (one way to remember is “hang on thight”) and the stalagmites sit below those on the floor. These dripstones from as water drips into the cave from the ceiling. As the water enters the cave opening it releases trapped carbon dioxide causing carbonate to from. More carbon dioxide is relased as the drop hits the floor again causing carbonate formation. Thus the stalagatites and stalagmites literally grow from the ceiling and floor eventually meeting up and forming columns. These formations take tens of thousands of years to form.
It’s a sharp position 🙂 OK, lame but I can’t think of anything else.
See, that’s how close my pawn was from queening in that unholy endgame!
Kinda lame too, but that’s all I can come up with for now…
I see a queen facing opposite of a rook. And a large hand moving one.
Mammoth cave, Kentucky? Just a guess.

Carlsbad caverns?
Luray?
Aggtelek?

The name of the formation is “Clyde”.
I would say one near san antonio, considering Susan is texan now.
the Stonewall formation.
Carlsbad Caverns, a 3-31/2 hour drive from Lubbock.

A sharp black opening.
I’d say Postojnska jama (Slovenia).
