Superior is a town in and the county seat of Mineral County, Montana, United States. Superior was named after its founders' hometown of Superior, Wisconsin in 1869. The post office was established in 1871 after Mineral County became the site of one of the largest gold strikes that helped settle the West.In the 1860s and 70s, several thousand miners converged on Cedar Creek to earn their fortunes. Long after that strike played out, mining remained a mainstay of the economy. Superior's elevation is 2,744 feet (836 Square Kilometer) above sea level. Superior is surrounded by mountains, right in the middle of the Bitterroot Range. The Clark Fork flows through downtown, heading north towards St. Regis, Montana and ultimately emptying into Lake Pend Oreille near Cabinet, Idaho.
