Yogo Gulch lies in a region originally inhabited by the Piegan Blackfeet people. Gold was first discovered at Yogo Creek in 1866, but the small numbers of early prospectors were driven off by local Native Americans. During a Gold Rush in 1878, about a thousand miners came to Yogo Creek, which was one of the gold-bearing streams in Montana not yet actively mined. "Blue pebbles" were noted along with small quantities of gold. The mining camp at Yogo City only flourished for roughly three years, and eventually the population dwindled to only a few people.
