https://en.wikipedia.org/wiki/Homestake_Mine_(South_Dakota)

"The Homestake Mine was a deep underground gold mine (8,000 feet or 2,438 m) located in Lead, South Dakota. Until it closed in 2002, it was the largest and deepest gold mine in the Western Hemisphere. The mine produced more than forty million troy ounces (43,900,000 oz; 1,240,000 kg) of gold during its lifetime. This is about 2,500 cubic feet (71 m3) or a volume of gold roughly equal to 18,677 US gallons.

...

In 1876, settlers Fred and Moses Manuel, Alex Engh, and Hank Harney discovered the Homestake deposit during the Black Hills Gold Rush. The Black Hills had been guaranteed to the Lakota Nation by the Fort Laramie Treaty, but the land was stolen for its gold."

When the illegal miners moved in on the Black Hills, Crazy Horse would on occasion raid them to sieze their gold, after which he would re-bury it.

Holy fucking badass move.
