Tepoto is a small coral atoll about two miles across. There is only one tiny pass to get into the lagoon and if the weather isn&#x27;t cooperating it is impossible to enter.    The legend of the treasure has it that in the late 19th century four mercinaries robbed several tons of gold from a church in Peru. They were making their escape to Australia but for some reason stopped in the Tuomotu islands of Polynesia and buried their loot on a small uninhabited island.
