What does "Idaho" mean?
Idaho is an invented word! Mining lobbyist George M. Willing presented the name "Idaho" to congress for a new territory around Pike's Peak, claiming it was a Native American Shoshone phrase: "E Dah Hoe (How)," supposedly meaning "Gem of the Mountains." By the time the deception was discovered, the name "Idaho" was already in common use. All State Name Origins
