A scientific analysis commissioned by the FBI shortly before agents went digging for buried treasure suggests that a huge quantity of gold could be below the surface of a rural site in western Pennsylvania. That’s according to newly released government documents and photos that deepen the mystery of the 2018 dig at Dent’s Run. The report was authored by a geophysicist who performed testing at the site. The government has long claimed its excavation did not yield any of the Civil War-era gold that legend says was buried there. The newly revealed geophysical survey was part of a court-ordered release of government records on the FBI’s treasure hunt.
