In 1881 four prospectors were leaving Grapevine Station (present day Barstow, California) for a mountain peak to the northeast. Describing the peak as "calico-colored", the peak, the mountain range to which it belonged, and the town that followed were all called Calico. The four prospectors discovered silver in the mountain and opened the Silver King Mine, which was California's largest silver producer in the mid-1880s. A post office was established in early 1882, and the Calico Print, a weekly newspaper, started publishing. The town soon supported three hotels, five general stores, a meat market, bars, brothels, and three restaurants and boarding houses. The county established a school district and a voting precinct. The town also had a deputy sheriff and two constables, two lawyers and a justice of the peace, five commissioners, and two doctors. There was also a Wells Fargo office and a telephone and telegraph service. At its height of silver production during 1883 and 1885, Calico had over 500 mines and a population of 1,200 people. Local badmen were buried in the Boot Hill cemetery.
