"Gallatin Valley: Captain Wm. Clark, of the Lewis & Clark Expedition, with a party of ten men passed through this valley July 14, 1896 eastward bound and guided by the Shoshone squaw Sacajawea. They camped that night at the toe of the mountains on the eastern edge of the valley. Captain Clark wrote in his journal: "I saw Elk, deer & Antelopes, and great deel of old signs of buffalow their roads is in every direction... emence quantities of beaver on this fork... and their dams very much impeed the navigation of it." In the early Sixties John Bozeman, young adventurer, and Jim Bridger, grand old man of the mountains, guided rival wagon trains of emigrants and gold seekers through here over the variously called Bonanza Trail, Bridger Cut-off or Bozeman Road from Fort Laramine, Wyo. to Virginia City, Mont. The trail crossed Indian country in direct violation of treaty and was a "cut-off" used by impatient pioneers who considered the time saving worth the danger. Traffic was not congested." - Erected by Montana State Highway Commission.
