| 説明 | Historical InformationAn 18 mile long peninsula protrudes in a northerly direction splitting Grand Traverse bay into east and west arms. Sitting on the 45th parallel and sheltered from major winds by the east and west points of the bay, the area had long been home to bands of Ottawa, who took up permanent residence on the narrow peninsula, planting potatoes and corn, and tapping the maples for their sweet sugar syrup. In accordance with the Treaty of 1836, the Federal Government agreed to provide the natives with both a mission and schools for their reservation, and on behalf of the federal government Henry Schoolcraft selected a natural harbor on the eastern shore of the peninsula for the planned facilities. Dispatched by the Presbyterian Board of Missions, the Reverend Peter Dougherty arrived in the harbor in 1838 to establish the mission for which the peninsula would eventually become known. With an increasing number of requests for the establishment of lighthouses throughout the Great Lakes, in 1863 the Lighthouse Board appointed a committee to conduct a review of recommended sites to report on the relative merits of each. Assigned to evaluate the site at Mission Point, Colonel James D. Graham of the Army Corps of Engineers reported that "there is an extensive trade in the two arms of this bay, the coasts and back country of which are thickly settled. At the heads of both these arms there are excellent harbors and good anchorage, and vessels should be aided in reaching them." With the end of the Civil War, and the country’s economy slowly improving, a site for the light on Old Mission Point was finally selected in 1869, and negotiations were underway with the owner to obtain clear title to the reservation.Work on the new station began on the opening of the 1870 navigation season. Plans for the station called for the erection of a 1 ½-story timber-framed dwelling with a short wooden tower integrated into the lakeward gable end. The tower was capped with an decagonal cast iron lantern, and stood 36 feet tall from the foundation to the top of the ventilator ball. Outfitted with a fixed white Fifth Order Fresnel lens, the structure’s location on a sand bank fourteen feet above the water’s surface provided the lens with focal plane of 47 feet, and was visible from a distance of 13 miles at sea. |
