The woodland surrounding the caverns were used as a game reserve by the Earl of Derby until 1939, when they became a storage facility for ammunition for the anti-aircraft position at Crank.
Beyond the roadway is an extensive network of tunnels, with access being possible through what is now a filled in entrance in a small patch of woodland just behind Crossdale Way, Moss Bank.
The Mousey is a smaller gated cavern next to the Elephant cave which leads into a much deeper and older set of tunnels.
The tunnels that are in the deepest section of this entrance are much older and feature long and vast stalactites and stalagmites compared to the Pillar and Stall method seen in the newer caverns.
