DescriptionThe discovery of silver on Granite Mountain in 1872 prompted development around the mines and stamp mill. By 1890, the population of Granite had swelled to 3,000, making it the state’s eleventh-largest city. The stone-and-brick Miners’ Union Hall functioned as the social center. When the silver market crashed in 1893, so did Granite. The mines experienced a brief recovery between 1898 and 1905, before the low price of silver forced closure of the mines once again, and another revival in 1910 when they started producing manganese. Today Granite is one of Montana’s most popular ghost towns and a state park, Granite Ghost Town State Park.Other Name(s)Granite MountainGranite Ghost Town State ParkContributing InstitutionMontana Historical Society Library and ArchivesGeolocation[1] Elevation7072 ft.CountyGranite County
