Mining originally brought settlers into what was called Harney City named after Harney Peak. Starting with the discovery of gold, Keystone was soon established as the town after the Keystone mine which was discovered in 1891. Although miners started the town, logging, Mt Rushmore National Memorial and tourism is what has kept the town alive. Although many mining towns were established throughout the Black Hills, very few have survived to the present day.
