Frisco developed as the post office and commercial center for the
San Francisco Mining District, and was the terminus of the
Utah Southern Railroad extension from
Milford. Frisco's fortunes changed suddenly on February 13, 1885, when the Horn Silver Mine caved in completely. It was an unconventional mine, an open pit deep braced with timbers, and could have collapsed at any time. In 1905 a
Mormon ward was organized, but in 1911, with the closing of many of the mines, so many church members had left that the ward was discontinued. After many years of desertion, another company made an attempt to mine here in 2002. ==Geography==
