A Lemhi Shoshone woman, who accompanied the Lewis and Clark Expedition, acting as an interpreter and guide, in their exploration of the Western United States between 1804 and 1806. She either died in 1812 (historical research) or 1884 (oral tradition). Since 2000, there has been a golden dollar coin minted each year with her image (it’s almost like real money).
