So, Cerro Gordo, the 300-acre ghost town, used to be the largest silver producer in California with about 4,000 people across 400 houses. Over its entire history, the inhabitants managed to mine around 17 million dollars worth of silver—500 million bucks today after adjusting for inflation.

But the mines ran dry, and so did the town. Brent is now the only resident in a 22-building town—actually, him, 7 cats, and 4 goats.
