The Garnet Range dominates the northern half of this Powell County landscape, where the peaks of Old Baldy Mtn and Bailey Mountain rise above a complex network of gulches and canyons. In the valley below, the Clark Fork and Little Blackfoot River converge near Garrison, a vital junction for the Northern Pacific and Chicago Milwaukee St Paul and Pacific railroads. This era represents a time when the rail-and-river economy was the primary driver of regional development, visible in the concentrated settlements along the tracks.
