We don’t have tunnels here in NW Arkansas as far as I know, but there are many many caves. Oh I suppose there are tunnels in Hot Springs, that place has been dug on here before, but the Mamman sculpture is at Crystal Bridges which is in Bentonville. Lots of caves.
Patagonia
Lots of energy reserves there iirc, also cool Dino bones.
