US explorer. Born in New York state, he became one of the most famous of the Mountain Men who opened up the American north-west. In 1824 he led the third expedition organized by fur-trader William Ashley (1778–1838) into Wyoming and in subsequent years made the first west–east crossing of the Sierra by a White man. Having opened more territory than any other explorer he was killed by a group of Comanche on the Santa Fe Trail.
