The Mammoth Mine was discovered around the same time as the settlement of Eureka in February 1870. Miners rushed in and began a boomtown. The area was remote and the environment harsh; no water was to be found nearby. The mines piped in water for industrial use, but residents had to buy drinking water for ten cents a gallon.

Mines in the area around Mammoth produced ore, silver, and gold. The Mammoth Mine was in production for around seventy-five years. Considered part of the Tintic Mining District, with other communities and mines in the area, the area around Mammoth played a vital role in the mining economy of the Utah Territory and later the State of Utah.

Activity in Mammoth peaked around 1900–1910, with a population of 2500–3000. The town had a school, four large hotels, and other businesses typical of a town its size. Mammoth was officially incorporated in 1910,but began to decline soon after. By 1930 the population was down to 750, and the town was disincorporated.
