This modern light doesn't merit inclusion on an official lighthouse list, as it never had a keeper or an enclosed lantern room, but if you are on Deer Island, you might as well stop by for a close-up view of the tower. Just offshore from the light is the Old Sow, the largest tidal whirlpool in the western hemisphere. The best time to see, and maybe even hear, the whirlpool is about three hours before high tide.
Known officially as Deer Point Light, the tower stands 6.1 metres (20 feet) tall and displays a two-second red flash every twelve seconds.
