Steamboat Arabia Museum.

In 1856, after striking a submerged tree trunk, 'The Arabia' sank with its 220 tons of cargo into the Misseuri River. In 1988, the Hawley family began excavation and three years later they opened the Steamboat Arabia Museum, displaying the "Treasures of the Steamboat Arabia". Although only half of the cargo - housewares, tools, food and personal effects - is on display restoration work still continues.
