The Arabia was a workhorse of the American interior, steaming up and down the Ohio, Mississippi and Missouri Rivers with mail, tools and other invaluable items. It sank in 1856 when it snagged on a submerged tree and ripped its hull. The wreck was rediscovered in 1987 and, given the shifting course of the Missouri River over the intervening 131 years, it was now half a mile inland under a farmer’s field. Over the next few months, the largest collection of pre-Civil War artefacts in the US was uncovered: there were gorgeous glass bottles (some containing still-edible pickles), beautiful beads and even weaponry. Many of these items, as well as the wreck's paddlewheel (pictured) are now in a dedicated museum in Kansas City.
