Missoula, Montana was founded in 1860 and named Hellgate Trading Post while still part of Washington Territory. By 1866, the settlement had moved five miles upstream and renamed Missoula Mills before being shortened to Missoula from the Native American Salish ‘’nmesuletk’ – “place of frozen water.” Fort Missoula was established in 1877 to protect settlers and with the arrival of the Northern Pacific Railway in 1883 the town was chartered the same year. The state’s first university, the University of Montana, was founded in 1893. Missoula County High School opened in 1908.
