National Register of Historic Places
Good forHistory buffs

East of Bozeman, a National Register site marks where the U.S. Army established a post in 1867 to protect settlers in the Gallatin Valley. Three years later, the Washburn-Langford-Doane Expedition departed from here for Yellowstone — the journey that helped set the national park idea in motion.
