well as Americans living there. In the same year, the Silver Purchase Act was enacted and drove down the price of silver. By 1896, its value had decreased to $0.57 per troy ounce, and Calico's silver mines were no longer economically viable. The post office was discontinued in 1898, and the school closed not long after. By the turn of the century, Calico was all but a ghost town, and with the end of borax mining in the region in 1907 the town was completely abandoned. Many of the original buildings were moved to Barstow, Daggett and Yermo. An attempt to revive the town was made in about 1915, when a cyanide plant was built to recover silver from the unprocessed Silver King Mine's deposits. Walter Knott and his wife Cordelia, founders of Knott's Berry Farm, were homesteaded at Newberry Springs around this time, and Knott helped build the redwood cyanide tanks for the plant. The last owner of Calico as a mine was Zenda Mining Company. After building Ghost Town at Knott’s Berry Farm in the 1940s, Walter Knott, his son, Russell, and Paul von Klieben, who was Knott's art director, made a road trip to Calico. The three of them came back filled with enthusiasm. If they could build an imaginary ghost town at Knott’s Berry Farm, would it not be possible to restore a real ghost town? In 1951, Walter Knott purchased the town of Calico from the Zenda Mining Company and put Paul von Klieben in charge of restoring it to its original condition, referencing old photographs. Using the old photos, and Walter’s memory and that of some old-timers who still lived in the area, von Klieben was able to not only restore existing structures, but also design and replace missing buildings. Knott spent $700,000 restoring Calico. Knott installed a longtime employee named Freddy "Calico Fred" Noller as resident caretaker and official greeter. In 1966 Walter Knott decided to donate the town to San Bernardino County, and Calico became a County Regional Park. Current status Calico has been restored to the look of the silver rush era when it flourished, although many original buildings were removed and replaced instead with gingerbread architecture and false façades that tourists would expect to see in a Western-themed town. Most of the restored and newly built buildings are made of wood with a simple, rustic architecture and a severely weathered
