We decided to check some spots that were pretty good to us on previous trips. The detector was deceptively simple with few buttons and auto-ground balance.

There weren’t as many pieces of gold, but what I did find was bigger. As I worked my way down towards the spot that I had been working the first three days, I noticed a large crack that crossed the river.

The father-son duo spent years combing this bit of Pennsylvania wilderness with high-end metal detectors, drills and other tools to prospect for a fabled cache of Civil War gold.

While none of the historical mining camps are active, the area is still a hub of activity for the modern prospector, and claims still blanket the hills and gulches.
