William Moon’s name is still associated with the Bear Flag Revolt of 1846, although there is no record that he took part in the action. However, as an American settler living near Tehama in Mexican California, he doubtless participated in heated discussions of resistance when word spread that General Castro had issued a proclamation that all Americans were to be driven out of the province. His link to the revolt is through his known association with Bear Flaggers William Ide, Ezekiel Merritt, and others. Born in Tennessee, Moon came overland to California in 1841, living in the Los Angeles area until he moved to Monterey, then to Tehama County, in 1845. He did some farming as a squatter, engaged in the business of mill stone quarrying, and was a well-known trapper. Since the property he settled on was adjacent to the pack trail route to the Shasta gold mines, he built a two-story traveler’s stop-over called the Moon House, the first all-timber house in Tehama County. He had so many requests to deliver messages, letters, and goods to travelers and packers that he installed a post office in his rest stop, recognized by the United States government and operated from 1851 to 1887. William Moon died in Tehama in 1875, aged sixty-nine.
