Route 555.

This is coolbert:

The Flying Dutchman Mine? The Treasure of Sierra Madre?

 No, the long-lost gold of Route 555, Pennsylvania, USA.

Long-lost and by repute a shipment of gold stolen and hidden over one-hundred and fifty years ago now. A shipment of gold stolen during wartime and never recovered. Until now? The jury is still out.

The screenplay for the Clint Eastwood western cinematic epic "The Good, The Bad and The Ugly" is based on this alleged incident? That article thanks to John Johnson.

"Legendary Lost Gold May Have Been Found"

"FBI agents and representatives of the Pennsylvania Department of Conservation and Natural Resources set up a base off Route 555 in Benezette Township, Elk County, Pa., at a site where treasure hunters say Civil War-era gold is buried."

"It's the stuff of legend: A wagon from the Union Army supposedly lost a huge cache of gold bars while en route from Wheeling, West Virginia, to the US Mint in Philadelphia in 1863."

. . . .

"That apparently changed last week as the excavation got underway. Various accounts say the Union wagon train was carrying 26 or 52 gold bars, which would be worth $27 million or $55 million, respectively, today."

Lone survivor. Ambush. Buried treasure. Time of war? The stuff of legend? We have heard it all before. The proof is in the pudding as they say?

See previous blog entries the topic of which was treasure of immense value as lost during a period of war, searched for but never found:
