Within this fence are the graves of five or six pioneers who died while traveling to the gold fields of California and the fertile Willamette Valley of Oregon. Alfred Corum and his brothers John, Herod, and Simeon left Cooper County, Missouri, on April 10, 1849. Their wagon train, bound for the gold fields, reached the Hams Fork Plateau on July 3, 1849, and remained there because Alfred had been sick for a week or ten days. About 200 wagons passed that day. On July 4, the wagon train moved on, leaving six men behind to aid the dying Alfred, who died at 1:00 p.m. of unknown causes on July 4, 1849. Margaret Campbell is buried a few yards from Alfred Corum; she died of unknown causes on July 29, 1848. Historians have not been able to determine the names and circumstances of death of the other emigrants buried here.
