Its rough reputation was boosted in 1881, when a mob of miners pulled Dutch Charley Burris, accused of the murder of a popular lawman, from a train and hanged him from a telegraph pole. Many Finnish men worked in the coal mines until 1902, when the mines closed. Today, there are only a few ruins to mark the site, but the Carbon Cemetery has been recently refurbished and is still being used.

The county’s history is rich in Paleo-Indian and bison-bone discoveries as well.
