Meramec Caverns is about an hour west of St. Louis. There's a lot of historic significance to this cave. The legendary Jesse James and his gang was said to use this cave as a hideout on several occasions. The cave was also used in conjunction with the Underground Railroad as a hideout for slaves. Even earlier in the cave's history, it was used as housing for the Indians in the area. Another part of history for this cave is ballroom dances were held in a large open area now near the main entrance to the underground.
