It retains an 1849 adobe ranch house and an 1858 adobe barn, plus a small adobe known as Wilson's store about a mile to the east.","why_significant":"From 1849 to 1861 the ranch was a famous camping spot and the first place emigrants could find food and shelter after crossing the desert on the Southern emigrant route. It also served as a Butterfield Overland Mail stage station from 1858 to 1861 and was a pioneering American cattle ranch. The surrounding valley has changed little since 1849, and the buildings give an unrestored picture of early conditions in the far west.","narrative":"Warner's Ranch is a remnant of a once 44,000-acre ranch in a quiet valley of San Diego County, California. The surviving headquarters includes a one-story adobe ranch house built in 1849 and an adobe barn erected in 1858, both partly covered with weatherboard but intact beneath. Cedar beams, hand-hewn timbers and wooden pegs were used in construction. About a mile east stands a small adobe called Wilson's store, also a wayside stop. Jonathan Trumbull Warner, a Connecticut native who became a Mexican citizen, received the land grants and built the ranch house to trade with arriving pioneers. From 1849 to 1861 the ranch was the first place where emigrants on the Southern route could find food and shelter after the desert crossing. It also served as a Butterfield Overland Mail stage station from 1858 to 1861 and as a cattle ranch. The buildings are badly deteriorated, though shored up and sheathed to slow further decay.","period_of_significance":"1849-1861","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Buildings are in very poor condition and deteriorated, with crumbling adobe walls protected by board sheathing; being preserved by the Vista Irrigation District with historical societies.
