Sacagawea (Hidatsa *Tsakákawia*, "bird woman") was the **Lemhi Shoshone woman who, at approximately 16 and carrying her infant son, served as interpreter and guide to the Lewis and Clark Expedition** (1804-1806) on its journey from the Mandan villages to the Pacific Ocean and back. **Her presence and that of her newborn signaled the expedition's peaceful intent to every tribe they encountered** — Clark wrote that no party with a woman could be considered a war party. **She is depicted on the US Sacagawea dollar coin minted since 2000**, and has more statues across the United States than any other woman.
Subject of Anna Lee Waldo's *Sacajawea* (1979) and many history books.
Sacagawea reduces to three — the number of Lewis and Clark's guide.
