A wagon buckboard is a simple four wheel wagon that is meant to be pulled by a large animal, such as a horse, a mule, or an ox. On March 3, 1850, Daniel Clayton and Martha O'Brien were married on the Oregon Trail. The date of their marriage was burned into a piece of a wagon buckboard, and kept by the couple as a reminder of their wedding day. On September 4, 1885, schoolteacher Clara Clayton was killed when she fell into Shonash Ravine after the horses pulling her rented wagon buckboard were spooked by a snake. The town later renamed the ravine Clayton Ravine in her memory.
