Underwater Caverns[1]

The Underwater Caverns are a series of caves located underwater, somewhere off the coast of the United States. The Underwater Caverns was the location of Fort Knox's gold reserves, which were brought there as protection from Hank and Ben, a couple of criminals who believed that gold was the root of all evil. They learned of the location regardless, and attempted to destroy the gold there, but they were stopped by the Superfriends.[2]
