Sacagawea was a Shoshone woman who played a significant role as an interpreter and guide for the Lewis and Clark Expedition, which was an American expedition from 1804 to 1806 that crossed the western portion of the United States to the Pacific Ocean. She is particularly remembered for her contributions to the success of the expedition, including her knowledge of the land, her ability to communicate with Native American tribes, and her resourcefulness. Sacagawea was also notable for being the only woman in the expedition's party, and for making the journey while she was pregnant and later caring for her infant son.
