In the 20th century, Axel Adler built a cabin on the former Bixby Ranch and gradually acquired more land. In 2013, descendants of the Adler family who lived in Sweden put of the Adler Ranch on the market for $15 million. It is located at the end and south of Palo Colorado Road. The ranch is located along the Little Sur River at the northwestern edge of the Ventana Wilderness adjacent to the Monterey Peninsula Regional Park District's Mill Creek Redwood Preserve. It is adjacent to Los Padres National Forest, Mill Creek Redwoods Preserve, and includes the peak of Bixby Mountain and the upper portions of Mescal Ridge. The El Sur Ranch and Pico Blanco Mountain are to the south. The tract along the Little Sur River contains old-growth redwoods, grasslands, oak woodlands, chaparral, and madrone forest. The ranch is an important habitat for California spotted owls, California condors, California red-legged frogs, marbled murrelets, and bald and golden eagles. The property is especially valuable because it includes nine legal parcels, five of which could be developed. The Big Sur Land Trust stated it was not interested in acquiring the property.
