The Big Sable Point Lighthouse is one of the few Michigan lights with a tower reaching 100 feet (30 m). Completed in 1867 Big Sable's tower measured 112 feet (34 m) high. In 1900 the deteriorating brick tower was encased in steel. The keeper's dwelling, which once housed a single family, has been enlarged over the years, resulting in the present three-family residence. Indoor plumbing and heating and a diesel electric generator were added in 1953. In 1953 power lines were extended to the Point. In 1966 the tradition of light-keeping begun in 1867 by Alonzo A. Hyde and his wife Laura ended when the station was fully automated. Big Sable Point Light Station is listed in the National Register of Historic Places.
