A search of vaults at the Sri Padmanabhaswamy temple found a vast collection of gold coins, jewels and precious stones worth an estimated $22 billion. (http://nyti.ms/n1Eoso)
Makes the Walter Mitty in me sit back and wonder what it must feel like to be able to forget about such a fortune. How does this happen? It is because it was gathered from poor people by the smarter leaders of the temple who went to the grave knowing this existed?
One of our visits on our recent trip was to the Steamboat Arabia in Kansas City MO, a Steamboat supply ship that sank in 1856 in the Missouri River. An almost intact cargo discovered when the ship was unearthed 1988 gave a unique view of what was needed to help settlers from the east populate the prairie-- the types of household goods, farm implements, clothes, guns, etc. that a steamship would carry to the then edge of USA "civilization".
In any case, for me, treasure hunting has always been a fascinating topic to think about.
