first rancher to ship sheep to San Francisco by steamer, some selling at $30 per animal. When Barron sold the island in 1869 to ten investors from San Francisco for $150,000, Shaw left for San Francisco and Los Alamos where he continued ranching. At that time, the gross proceeds from the ranch on Santa Cruz Island were supposedly $50,000.
One of the investors, Justinian Caire, was a French immigrant and founder of a successful San Francisco hardware business that sold equipment to miners. By the late 1880s Caire had acquired all of the shares of the Santa Cruz Island Company which he and his colleagues had founded in 1869. He continued a successful livestock and ranching industry on the island for many years.
An extended and complicated series of litigation among Caire family members resulted in the division of the island and the sale of most of it in 1937. Justinian Caire's descendents retained 6,000 acres (24 km) on the east end of the island, on which they continued the sheep ranching operation. Other family members sold the remaining 90 percent of the island to Los Angeles oilman Edwin Stanton in 1937.
Edwin Stanton’s purchase of the major part of Santa Cruz Island brought a major shift in agricultural production on the island. After trying for a short time to continue the sheep operation, he decided to switch to beef production. At the time, the beef industry in California was growing rapidly, with Santa Barbara County among the top ten beef producers in the state.
Edwin Stanton’s ranch on Santa Cruz Island saw changes that reflected the evolution of cattle ranching in a working landscape. While retaining most of the 19th century structures dating from the Caire period, Stanton constructed a few buildings to meet the needs of his cattle ranch, the most notable of which is Rancho del Norte on the isthmus. Pasture fencing and corrals were altered to suit the cattle operation and an extensive water system was added to
