Warner Ranch, Ranch House, San Felipe Road (State Highway S2), Warner Springs, San Diego County, CA

Structure is associated with the Santa Fe Trail, Camp Wright, & the Battle of San Pasqual.
Significance: The Warner Ranch is a Registered National Historic Landmark and California Historical Landmark #311. It was the focal point for emigrants traveling over the Santa Fe Trail to the California settlements and gold fields from 1844; and it served as a way-station for Butterfield's Overland Mail Company from September 16, 1858, until April, 1861. It was the first well supplied trading post reached by emigrants after the long trek across the southwest deserts. It figures prominently in events incident with the arrival of the Army of the West under command of General Stephen Watts Kearny during the United States war with Mexico and the Battle of San Pasqual which was the sharpest engagement in the conquest of California. During the Civil War, Camp Wright was established on the ranch for the final staging of the California Volunteer Battalion under Colonel James H. Carleton. The buildings, extant, are of adobe brick and hand-hewn timbers put together by mortise and tenon and wood pegs, typical of the early west.
