He was the youngest member of the famous Lewis and Clark Expedition of 1804-1806 as the infant son of their Lemhi Shoshone Native American woman guide Sacagawea (c.1788-1812), who carried him as a baby / toddler strapped to her back in a papoose as she guided the white Americans William Clark (1770-1838) and Meriwether Lewis (1774-1809), and their Corps of Discovery on orders from third President Thomas Jefferson (1743-1826, served 1801-1809), charting the newly-acquired immense tract of unexplored lands west of the Mississippi River from the First French Empire (France) of their new Emperor Napoleon I of the enormous tract of the Louisiana Purchase of 1803.

After traveling northwest upstream on the Missouri River, she guided them through the wilderness passes in the Rocky Mountains chain going westward eventually through the uncharted Pacific Northwest region, along the Snake and Columbia Rivers to the West Coast and the Pacific Ocean, then eventually returning back east.
