Looks kind of like a hooded pitcher plant. Two things I like, caves and carnivorous plants. Too bad their are no carnivorous plants that live in caves.

Cool pic.

Looks similar enough to the Cobra Lily!

Yeah, my first thought was a cobra too. So, where is that cave?

This formation is in "Cave Without a Name" near Austin, Texas. You can look at more pictures at cavewithoutaname.com . The caverns at Sonora are more beautiful though. I don't know what they named this formation... there are usually descriptive names.
