Mountain Gem was a sternwheel-driven steamboat that operated on the Snake and Columbia rivers from 1904 to 1912, when the machinery was removed and installed in a different, newly built steamboat. Mountain Gem remained on the U.S. merchant vessel registry until 1922 or later. Although Mountain Gem was not abandoned until 1924, there is no evidence it was used after 1912.
