A fertile valley hemmed in by mountains cradles Missoula, the cultural center of northwest Montana. The largest metropolis around (population 68,000) is the home of the University of Montana. In the aptly nicknamed Garden City, maple trees line the residential streets and the Clark Fork River meanders through the center of town; a 6-mile riverside trail passes the university en route to Hellgate Canyon. Missoula makes a good base for regional exploration by way of Interstate 90 east–west, U.S. 93 north–south, and numerous back roads.
In 1860 French trappers dubbed this trading settlement the Hell Gate when they discovered bones and bodies in the canyon after a bloody battle between Blackfeet and other Native Americans. Settlers did not arrive until more than 50 years after the Lewis and Clark expedition traveled through the area. Gold speculators, homesteaders, and the coming of the Northern Pacific Railroad in 1883 all helped establish the town.
