Mammoth Cave is a popular tourist destination in the United States of America.
Seemingly located in the state of Kentucky, Mammoth Cave was one of the location marked out on a giveaway Vacation Map which Donald Duck used in 1942 to plan out the long vacation trip he planned on taking with his nephews using the money acquired from Henry Morgan's treasure. Whether the Ducks actually put this plan in motion after finding the treasure is unclear.
Behind the scenesEdit
The name of Mammoth Cave appears in the 1942 story Donald Duck Finds Pirate Gold. The comic does not elaborate on its nature; in the real world, Mammoth Cave Nation Park is a national park in the state of Kentucky, containing the titular cave, notable as the largest known cave system on Earth.
