Pirate Sir Francis Drake Treasure Bullion Stash

1579 Sir Francis Drake heads out to pillage Spanish West Coast (Mexico). The problem was getting back across the fierce Pacific Ocean. His ship the Golden Hinde was burdened with gold bullion tonnage plundered from the Spanish. Drake must stash some of this treasure some on the British Columbia island studded coast to make room for tonnage of water and wood. Where is Drake's stash?
