	"Idaho" is an invented word. The meaning is unknown. Mining lobbyist George Maurice "Doc" Willing (* 1829, † 1874) presented the name "Idaho" to US Congress in 1860 for a new territory around Pike's Peak, claiming it was a Shoshone Indian word meaning "Gem of the Mountains". By the time the deception was discovered, the name "Idaho" was already in common use. Find out more facts & trivia
