Well here is one that surpasses the Fenn's cache. It contains 6 brass chests filled with gold and silver coins, gems like rubies and eneralds, rare artifact, etc. There are also 6 smaller containers and a glass skull fulled with loot. The clues are in a novel,"Gallows Harbor, Blood Feud" which is in the kickstart program right now. This ghost town is on the west branch of the Susquehanna River In Clearfield Co. PA.
I have been prospecting and treasure hunting all over the USA since the '70s and this is the biggest cache I have seen so far.
