Another one of the US' abandoned mining towns, Garnet dates back to the 1860s. It was once the residential and commercial center for a heavily mined area. It is believed that in 1898, around 1,000 people populated the town that was once known as Mitchell. Unsurprisingly, Garnet was abandoned two decades later when the gold in the mines ran out. Despite suffering from a fire that destroyed half of the town in 1912, Garnet is now one of the state's best-preserved ghost towns and has 16,000 visitors annually.
