Three Forks, Montana: July 27, 1805

Sacagawea led the expedition to this site where three tributaries converge to form the Missouri River. Ironically, this was also the place where Sacagawea had been kidnapped five years earlier by the Hidatsa. The three rivers were given the names of Madison, Gallatin, and Jefferson. After some reconnaissance and much discussion, the two leaders decided that the Jefferson River was the most likely to lead directly to the Continental Divide.
