Claus Spreckels, the Sugar King, picked a bluff over the dry Salinas River in 1897 for what local accounts called the world's largest beet-sugar factory. Around it he built wells, a railroad, a contract system, and a company town. The pumping began drawing down the valley's underground river, and the work was divided by race between field and factory. The last beets arrived in 1982.
Whether the plant was the largest beet-sugar factory in the world or the largest refinery in the country depends on what is counted. Capacity figures, the incorporation and opening dates, and the closure year (1981 or 1982) vary by source, and the 1929 acreage collapse needs verification.
