The site design is somewhat unfortunate, but The Virtual Cave features lots of photos and information on, well, caves and cave formations. We've all heard of stalagmites and stalactites, but I'd never heard of cave draperies or cave pearls before. Then you've got your helictites, your aragonite, and your splash stalactites (found in lava tubes). And they've got a Show Caves Directory of caves in the United States that are open to the public, with addresses and contact information by state.
