Default Re: 5: 29 June 2009 - Caves

Very definitely. We have a lot of "wet" caves here in Missouri, but one of the most famous, the cave in Mark Twain's Tom Sawyer isn't a true "wet" cave where you find the limestone stalagmites and stalagtites. Most of it is under a "shelf" of bedrock which deflects the water that would form them. There are a very few formations in there. The cave was formed by the Mississippi River washing the mud out of the rock. So when you see drawings of Tom And Becky Thatcher exploring huge rooms filled with limestone formations, they're nothing more than fantasy. The biggest room in the cave is about 40 to 45 feet long by about 13 or 20 wide, with a ceiling about 10 or 15 feet high.

Onondaga and Merrimac, as well as others here are huge by comparison.
