In May 1805, as the Lewis and Clark expedition paddled up the Missouri River, a howling gust of wind tipped over one of the canoes. The men paddled to shore, leaving behind precious supplies. Instantly, Sacagawea jumped in the water, rescuing important journals and scientific experiments. Throughout Lewis and Clark's journey in the uncharted American West, this young American Indian woman proved to be an invaluable member of the expedition. Sacagawea served as translator and guide, all while caring for her infant son. Sacagawea's life may have been short, but her exploits on this mission made her a legendary American.
