Jim Kennedy has correctly guessed #1 & #2 The names of all 3 caves are all over the web on the real-estate ads for these 2 parcels.
It would seem possible just to buy the entrances, then get some kind of easement, especially for #1, which should be a #1 priority for anyone in the U.S. considering a cave purchase, as it is so close to the main road for miles and miles, and super easy for locals to access. David Locklear
