Challis, ID

Bayhorse is a ghost town founded in 1877, though active development of the town did not begin until 1880. Bayhorse was once a thriving mining town, largely supported by large silver deposit. In 1882, the town increased its smelting capabilities, producing $300,000 worth of silver over the course of the year. By 1885, the town had grown to 300 residents, supported by a mill, three stores, a hotel, a restaurant, a meat market, a lodging house, and five saloons. The same year, the town built a refinery, allowing the mining industry to issue silver bars and by 1900, the town had extracted over $10 million in total ores, including silver, lead, and copper. The town was abandoned by the 1920s.

In 1976, the entire community was added to the National Register of Historic Places. The town property was purchased by the state in 2006 and opened to the public in 2009 as part of the Land of the Yankee Fork State Park.
