Elkhorn is acensus-designated place (CDP) inJefferson County,Montana, United States, in theElkhorn Mountains of the southwestern part of the state. As of the2010 census it had a population of 10.[3] The community is considered aghost town,[4][5] and two of its buildings are preserved asElkhorn State Park.[6][4]
Lodes ofsilver, described by geologists assupergene enrichments, were initially discovered in the Elkhorn Mountains by Peter Wys, aSwiss immigrant.[7] Six years later, Anton Holter, a pioneer capitalist fromHelena, began developing the mine. Over $14 million in silver was carried from the mine. In 1890, theSherman Silver Purchase Act passed, creating a high demand for Elkhorn's silver.
During this peak period, Elkhorn had 2,500 inhabitants, a school, a hotel, a church, stores, saloons, and brothels. Unlike most mining towns, Elkhorn was populated mostly by families of married European immigrants.[8] In 1893, the Fraternity Hall was constructed for social gatherings, and still remains as one of the most well-preserved buildings in modern Elkhorn.
In the years following, the silver boom and Elkhorn's prosperity began to lessen as the desire for silver decreased. Adiphtheria epidemic struck Elkhorn in the winter of 1888–1889, resulting in many deaths, particularly of children.[8] Soon after, railroad service to Elkhorn was halted and only a fraction of the original inhabitants remained.
The state of Montana designated Fraternity Hall and Gillian Hall as Elkhorn State Park in 1980.[9]
