        Poe
        Reef lies just eight feet beneath the water's surface between Bois
        Blanc Island and the Lower Peninsula mainland, and as such has long
        represented a significant hazard to vessels making their way through the
        Straits between Lakes Michigan and Huron.
         
        In the early 1890's the Lighthouse
        Board faced a vexing problem. Increasing vessel traffic created a
        need to install navigational aids at a number of offshore shoals and
        reefs. With Congressional funds increasingly difficult to obtain, and
        the costs of offshore lighthouse construction prohibitively high, the
        Board determined that the use of lightships to mark such hazards would
        be both significantly more expeditious and cost effective. 
        Unable to convince Congress to free up
        the funds for these lightships, the Board took the chance of redirecting an
        existing $60,000 congressional appropriation for a lighthouse off
        Peninsula Point to the purchase of four lightships. 
         In 1892 two contracts totaling
        $55,960 were awarded to the Craig Shipbuilding Company in Toledo for the
        construction of four lightships. Designated as Lightships LV59, LV60,
        LV61 and LV62, all four vessels were built to similar specifications.
        Framed and planked of white oak they measured 87' 2" inches in
        length, 21' 6" inches in the beam, with a draft of 8 feet. In a
        cost-cutting effort, the vessels were un-powered, outfitted with only a
        small riding sail carried on a short after mast. Equipped with a cluster
        of three oil-burning lens lanterns hoisted on their foremasts, each was
        also equipped with 6" steam whistles and hand-operated bells for
        fog use. Work was completed on the four vessels
        the following year, and after sea trials, all four were commissioned by
        the Board and placed into service, LV59 being assigned to Bar Point,
        LV60 to Eleven Foot Shoal, LV61 to Corsica Shoal and LV62 to Poe Reef. 
         With the words POE REEF brightly
        painted in white on her fire engine red hull, LV62 was towed to Poe Reef
        by the lighthouse tender Marigold, and anchored on station to begin her
        vigil on September 29, 1893. For the next seventeen years LV62 spent
        every shipping season faithfully guarding the shoal. With the end of
        each shipping season, one of the lighthouse tenders would make the
        rounds of all lightship stations in the Straits area, and tow them into
        Cheboygan harbor for winter lay-up. While in Cheboygan, necessary
        repairs and improvements would be made in preparation for the following
        season. At some time in March or April, the ice would break up
        sufficiently to allow the vessels to be towed back to their stations to
        stand guard for yet another season. 
        1910 would be LV62's last season on Poe
        Reef, since for reasons we have as yet been unable to determine the
        decision was made to trade assignments at Bar Point with LV59. LV59
        was delivered to Poe Reef at the beginning of the 1911 shipping season,
        remained at the reef for the following three seasons. During a
        departmental survey of lightships in the fall of 1914, she was found to
        be unseaworthy and thus condemned at the end of the season. To replace
        her, LV96 was repainted with POE on her sides, and transferred from
        Buffalo to Poe Reef at the beginning of the 1915 navigation season. 
         Built by Racine-Truscott-Shell Lake
        Boat Company in Muskegon in 1914 at a total cost of $71,292, LV96 had
        only seen one year of service at her Buffalo station before her
        transfer. 101' 6" in length, 23' 6" in beam and drawing 9'
        5", she was constructed of steel in the whaleback design, with her
        pilot house forward. Equipped with electrical generators and batteries
        powered by two 3-cylinder kerosene engines, she displayed a large
        cylindrical lantern housing with a thousand-candlepower electric lamp. A
        revolving parabolic reflector provided her with a unique light
        signature. A six-inch air siren, submarine bell and a hand operated bell
        made her presence known whenever fog shrouded the reef. 
        In the spring of 1921, LV96 was
        reassigned to duty on Corsica Shoal in Lake Huron and the newly
        commissioned LV99 was delivered to Poe Reef in her place. 
        LV99 had her keel laid in June of 1919
        at Rice Brothers in Boothbay Harbor, Maine, and work was well underway
        on July 10 when a fire gutted the structure. With new materials
        procured, the vessel was completely rebuilt at a total cost $97,220, and
        she was launched on November 7 of that same year. 91' 8" in length,
        with a beam of 22' she drew 10' 7" and was powered by a
        single-cylinder 125hp steam engine. Displaying a single acetylene lens
        lantern, she was also equipped with a ten-inch steam whistle and a hand
        operated bell. 
        As part of a series of a significant
        offshore light construction projects being undertaken in the Straits
        area in the late 1920's, the Lighthouse Service decided to build a
        permanent station on Poe Reef in 1927. 
         For two years, an 80-man construction
        crew had been working out of a base camp on Government Island in Les
        Cheneaux Islands, while they undertook the mammoth task of building the 
        Martin Reef Light. With the completion of that project in the summer of
        1927, the entire base camp was loaded onto the lighthouse tenders ASPEN and
        MARIGOLD, and rebuilt on the north pier at the mouth of the
        Cheboygan River. With establishment of the camp, construction at Poe
        Reef Light began on two fronts. 
        Construction plans called for the
        placement of a sixty-four foot square wooden crib on the reef to serve
        as a foundation for the pier on which the tower would be constructed. In
        order to prepare the reef for the crib's installation, an area first had
        to be leveled and cleared of all rocks and boulders. For this task,
        Lighthouse Service Scow #1 was equipped with a steam-powered derrick and
        a clamshell bucket. Towed out to the reef by the lighthouse tender ASPEN, and anchored at the edge of the reef, hardhat divers assisted in
        guiding the scow's clamshell. 
        Back at the Cheboygan pier with the
        construction of a skid way complete, the timbers of the crib itself were
        assembled on top of the skid way. Constructed of dressed 12" by
        12" timbers, the crib was a sixty-four feet square and featured
        tightly crafted half-lap joints throughout in order to provide the
        utmost in structural rigidity. With the outer walls constructed in an
        elongated brick pattern, each joint was hand-drilled and bolted, and
        iron angles added to the corners for even more strength. Finally, the
        upper exterior surfaces were sheathed with steel plates protruding six
        feet above the sides. These steel plates designed to create the exterior
        forms into which the concrete of the pier itself would be poured once
        the crib was positioned on the reef. 
         With preparatory work complete on the
        reef, the lighthouse tenders ASPEN and MARIGOLD pulled the completed
        crib down the skid way, into the water, and thence into the lake to the
        reef, where it was carefully positioned over the prepared area on the
        reef. Crushed limestone and rocks were then dumped into the crib from a
        self-unloading lake freighter until the crib sank to the bottom, resting
        on the leveled area of the reef. With the crib completely filled with
        limestone and rocks, Scow #1 was outfitted with a gasoline powered
        cement mixer, a wooden tower, hopper and discharge chute. With concrete
        from the mixer dumped into the hopper, the hopper was raised to the top
        of the tower and dumped into the discharge chute. This chute was then
        pivoted across the surface of the crib, allowing crewmembers to
        distribute the concrete evenly until it was filled to the top of the
        steel plates rimming the crib. By virtue of the base camp's location in
        Cheboygan, dependent on weather conditions either the  Aspen or the
        crew's work boat would transport the crew to the reef at the start of
        each day's work, returning to transport them back to camp at day's end. 
         With the final pour to the upper limit
        of the steel sheathing, the entire top surface of the concrete was
        carefully leveled through the use of a transit. It was critical that
        this upper surface be completely plumb, since it was the foundation on
        which the pier and the lighthouse itself would stand. Once level was
        established, the first of a series wooden forms which had been
        prefabricated back at the camp, were attached to the outside of the
        structure. As the form for each level was filled with concrete, the next
        level of forms was added above. Like a giant puzzle, each form created
        different sections of the ladder accesses on each of the four sides, the
        arch-topped storage areas within the pier, and finally the wave flare at
        the top of the pier. This wave flare was a vital component of the crib's
        design, since it was designed to divert waves crashing against the pier,
        thus reducing the likelihood of wave action smashing against the tower
        itself. With the pouring of the final level, anchoring points for the
        light station structure itself and the posts around the outer edge were
        cast in place. 
        With the setting of this final layer of
        concrete, the bunkhouse on the pier in Cheboygan was loaded onto the 
        Aspen and transported to the reef, where it was lifted onto the pier.
        With the construction of a temporary cook shed, the crew was able to
        take up residence at the work site, and the workdays grew longer with
        the elimination of the daily commute from Cheboygan. The crew's
        attention now turned to the construction of the tower itself. 
         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. 
        With construction at the reef complete
        in late 1929, the bunkhouse and cook shack were loaded back onto the
        tender Aspen, and returned to Cheboygan, where the camp was readying to
        begin construction of a new light on Fourteen Foot Shoal. 
        The light was automated in 1974 with
        the installation of a solar-powered 375mm acrylic optic.
