The cave of treasures.. eh no.. It's the biggest room inside the Natural Bridge Caverns in San Antonio, TX. 5000 year old caverns with stalactites, stalagmites, draperies and plenty of still-mushy bat shit. There's even an adventure tour where you crawl through the narrow caverns like the original explorers! It's a pain to photograph though, since you can't touch anything, and you need to place your camera somewhere to keep it steady..
