Gallatin River
The "Canyon" area of Big Sky lies in the Gallatin Canyon, along the Gallatin River, a favorite for white water rafters and kayakers. The Gallatin River, named after Albert Gallatin who was the Secretary of the Treasury during the Lewis and Clark Expedition, is a Blue Ribbon trout stream that attracts fly-fishers from around the world. Several dude ranches (320 Guest Ranch, Elkhorn Ranch, Cinnamon Lodge and 9 Quarter Circle) operate in the Gallatin Canyon.
