Poe Reef Light

Terry Pepper has (as usual) a very detailed entry for Poe Reef Lighthouse on his Seeing the Light website. This crib style lighthouse is located off Bois Blanc Island in Lake Huron. The reef is very close to the surface and posed a significant threat to navigation until the decision was made in the 1890s to anchor a lightship there. This served until Lighthouse Service decided to build a permanent station on Poe Reef in 1927:

The station building at Poe Reef was to be an exact duplicate of that which the crew had previously completed at Martins Reef. The main twenty-five foot square structure consisted of a steel skeletal framework to which an exterior sheathing of riveted steel plates was applied. Thirty-eight feet tall, it contained three levels, or “decks”, as the crews assigned to the station knew them. The two upper decks were set up as living quarters, while the main lower deck served as housing for the machinery required for powering the lights, heating system and foghorn.

Centered atop the main structure stood sixteen-foot square, ten-foot high watch room of similar construction, with a single observation window on each side. Finally, a decagonal cast iron lantern room was installed on the roof of the watch room, and outfitted with a Third Order Fresnel lens. The combination of pier and tower provided the Fresnel with a seventy-one foot focal plane, and a visibility range of almost twenty nautical miles in clear conditions. Work was completed at the station and the light exhibited for the first time on the evening of August 15, 1929.

At some point in time, in order to eliminate the possibility of the Poe Reef Light being mistaken for the identical all white structure at Martin Reef, the main deck and watch room of the Poe structure were given a contrasting coat of black paint.

Terry has some cool shots of this light as well including this wide shot with cormorants.
