2012 Robber Baron Cave Map

This map is a complete redraft, based largely on the 1976–77 survey with newer surveys used for additional passages and to improve the quality of the original in some areas. It uses a computer generated line plot as the backbone of the map to maximize its accuracy. Drafted by Joe Mitchell.

1978 Robber Baron Cave Map

This version was used for more than 30 years as the definitive map of the cave and formed the basis of the newer map. Drafted by Randy Waters.

1921 North Loop Cave Map

This is the oldest known map of Robber Baron Cave Map (then called North Loop Cave) and predates commercialization. Note that the North arrow actually points southwest, and the entrance is the currently-unused Historic Entrance. Some of the room and passage names in this map were previously unknown but were added to the 2012 map as a nod to the early history of the cave. Drafted by the U.S. Signal Corps.
