Two other post offices opened and closed inside today’s town.
The post office was established June 5, 1871, and temporarily closed October 19, 1883, before being reopened December 12, 1883. It was permanently closed on July 31, 1964.
In 1912, Silverdale was described as a hamlet with a hotel, general store, bank, and other businesses, and in 1910 the population was 100. Today only a church and limestone quarry remain with perhaps a dozen residences. The quarry specialized in fine cut, quality limestone.
