Knowles, California

Knowles (formerly, Dusy's Rock Pile) is an unincorporated community in Madera County, California. It is located 2 mi east of Raymond, at an elevation of 928 feet (283 m).

A post office operated at Knowles from 1902 to 1955. The name honors F. E. Knowles, owner of a local granite quarry. Knowles was a thriving granite quarrying community in the early 1900s, with a hotel, saloons, and a railroad stop, but by 1963 the town was described as a "ghost community". A granite quarry remains at the site today, although little else remains of the town.
