Whatever happened to Sacagawea's son? His mother became a legend. But the infant boy who also made the hazardous 1,900-mile journey to Oregon with the Lewis and Clark Expedition nearly disappeared from sight after their return. Yet he lived a long, adventurous life. Educated in St. Louis by William Clark, he spent six years in Europe as the ward of a German prince. Upon his return he joined the fur trade, working with the famous of the west--Jim Bridger, Tom Fitzpatrick, Kit Carson--a guide for the Mormon Battalion in its 1,100-mile march across the Southwest to California, the alcalde of Mission San Luis Rey, and a gold miner. He died, in a remote corner of Southeastern Oregon, at age 61.
