The Vessel and Her Loss
The Palo Alto was one of a small number of concrete steamships built at the end of the First World War. In 1930 she was towed to Seacliff, sunk in place at the end of a pier and fitted out as a floating amusement resort. The venture soon failed, and the abandoned hull has been broken apart by decades of storms. Her remains are part of Seacliff State Beach.
