The diary of 17 year old Alvin McDonald is a fascinating primary document about the exploration of Wind Cave. Like Stephen Bishop at Mammoth Cave, Alvin mapped and named many of the rooms in the cave. He died of Typhoid fever at the age of 20.

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.
