Often built in isolated locations, miles from cities and towns, lighthouses have developed a certain mysterious charm and romantic aura over the years. Although the lighthouse keepers of old are gone, lighthouses with automated lights continue their important work of helping ships to reach their destination safely. Five important lighthouses were honored on U.S. stamps for their place in American history. They have safely guided untold numbers of ships through dangerous Pacific coastal waters. Located off California’s northern coast, St. George Reef Lighthouse marks a hazardous reef six miles from California’s shore, near Crescent City. It was first lit in 1892 and deactivated in 1975 because it was considered dangerous for light keepers to get to. It was re-lit in 2002.
