There are extensive cave formations in Kentucky (Mammoth Cave is one).  The extent is so vast that I doubt they have been fully explored.

This whole area was once at the bottom of a shallow sea, and the buildup of carbonates from that created a huge limestone substrate of bedrock. Once it was raised from the bed of that sea to dry land, the action of water over millions of years hollowed out that limestone into a warren of caves honeycombing the entire area, what is known geologically as a "karst" terrain. There are most definitely caves here that have never been fully explored. I know of places one can travel for miles underground and never see daylight, and still never know where that cave ends.

"Burial Caves" are still occasionally newly discovered here, but it's illegal to poke around in them and explore them for anyone but archaeologists.
