Rancho San Francisco

Approximately one-half mile south of this point was the adobe headquarters of Rancho San Francisco, originally built about 1804 as a granary of Mission San Fernando. The rancho was granted to Antonio de Valle in 1839. Here, in January 1850, William Lewis Manly and John Rogers obtained supplies and animals to rescue their comrades in a California-bound gold-seeking emigrant party that was stranded and starving in Death Valley, some 250 miles to the northeast.

Plaque placed by the California State Park Commission in cooperation with the Los Angeles County Board of Supervisors and the Death Valley '49ers.  November 6, 1959.
