This is said to be the world's largest free-standing boulder. It's called Giant Rock. Guess they were out of clever names that day. Wagner suggests a better name: Wagnerok. (Get it? Ragnarok? Forget it about it.)
Wagner points out the entrance to the underground rooms carved out beneath Giant Rock. A miner blew himself up ("or was blown up," Daniel Boone suggests) with the dynamite he stored here. Van Tassel later lived at Giant Rock, using the rooms for storage.
