Rancho Butano was sold in 1862 to Clark & Coburn of San Francisco. Loren Coburn, born in Vermont, came to California in 1851, and worked first in mining. Loren Coburn bought out his brother-in-law Jeremiah Clark. 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. Pescadero Marsh remained an un-important feature to Mr. Coburn, and at that time there were no formal roads through it, although cattle grazed freely throughout the marsh as it remained unfenced.Historic Properties Survey Report for San Mateo Co.
