If you get the chance, the lava tubes in northern California are pretty cool too.

I'll have to keep that in mind if I'm ever in the area.
Very cool pictures. I love the drapery formation.
Probably an unpopular opinion but Marengo Cave looks more interesting than Mammoth Cave. Mammoth is cool and worth visiting but a lot of it is dry so not a lot of formations.
My favorite cave/cavern in the park system that I have visited is Carlsbad Cavern. Absolutely spectacular.
The drapes tended to be some of my favorite formations too. I think because they look since they look so flowing that my brain, despite knowing better, would expect them to be soft and malleable almost like parts of some giant science fiction horror movie beast. My favorite thing in the cave was probably the large pools that were so still that they created a perfect mirror that it made it look like a giant pit. It was so mind trippy when falling droplets would create small ripples that made it look almost like some mirror universe. Sadly the lighting was so low and the ripples so delicate that my camera just couldn't capture it well enough to do it anywhere near justice.
