The grant extended along the Pacific coast between Rancho Pescadero and Rancho Punta del Año Nuevo, with Butano Creek on the north to Arroyo de los Frijoles (Creek of the Beans) on the south, and encompassed present-day Bean Hollow State Beach and Butano State Park.
With the cession of California to the United States following the Mexican-American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored.
Coburn subsequently bought Rancho Punta del Año Nuevo directly to the south.
He was an extremely aggressive land owner, contesting boundaries, and a perpetual litigant in the courts, and was widely disliked.
In the 1890s, Coburn erected a large hotel on the bluff above Pebble Beach, hoping to make it a popular destination for vacationers taking the planned Ocean Shore Railroad from San Francisco.
[11] Coburn leased much of the land to a dairy enterprise run by the Steele family (Rensselaer, Isaac and Edgar) from Delaware.
