Its northern end belongs to the original ranchhouse erected in the 1850s, and later additions have enlarged the structure. The site is listed because it is one of perhaps several stations still standing along the Butterfield Overland Mail route. That service carried mail and passengers from September 1858 to March 1861 over a 2,795-mile course between San Francisco and the eastern termini of St. Louis and Memphis. Way-stations like this one acted as ticket offices and inns, built from whatever material was at hand, including adobe brick. During the Civil War the building served as a hospital for Camp Wright, which occupied ground across the highway. Old oak trees still shade the setting, though sheds, gas pumps and debris surround the building. The northern end remains a residence, and the rest is sometimes used as a store.","period_of_significance":"1858-1861","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Described as well preserved and occupied; the northern end is used as a residence and the rest is sometimes used as a general store.
