}} Tawas Point Light is located in the Tawas Point State Park off Tawas Bay in Lake Huron in Baldwin Township in Northern Michigan. ==History== In 1850, Congress appropriated $5,000 for the construction of a lighthouse. In 1852, construction started, and the lighthouse was commissioned in 1853. After the lighthouse was built, many problems were encountered. Shifting sands caused the point to be extended by nearly a mile. The original light was a 5th Order Fresnel lens, later upgraded when the building was replaced. In 1867, the Inspector of the lighthouse said that the lighthouse was wearing down to the point where they should consider renovating it. The Lighthouse Board ignored his request to put more money in the lighthouse because they had bigger problems at hand in Ottawa Point. The waves caused sand build-up by the Point, which added almost a mile, more of land. The lighthouse was so far inland that mariners were unable to see the lighthouse's light. To add to the problem this lighthouse was known for its dim light. With all these problems combined, it caused a shipwreck from Captain Olmstead's schooner "Dolphin". He blamed the lighthouse stating that it was too dim to see the light. This caused the Lighthouse board to reconsider their option at renovating or rebuilding a new one. In 1875 Congress approved a $30,000 amount for a brand new lighthouse. They finished building the lighthouse sometime in 1877.〔http://www.terrypepper.com/lights/huron/tawas/tawas.htm〕 It was originally known as Ottawa Point. The name was officially changed to Tawas Point in 1902. The point is a substantial hazard to navigation. Additionally, because it is tucked behind the point, Tawas Bay is an ideal shelter from storms, wind and waves out of the north and northeast. The point juts out into Lake Huron, and has been getting much larger over time. A map is available, which shows the accretion. The original light was begun in 1852, and completed in 1853. The light was fueled at various times by lard oil, then kerosene, and the current light is of course now electric. This is the second lighthouse on the point.〔(Tawas Point light house geography and history )〕 The tower is tall including the base, with a diameter at base of and a diameter at parapet of It is constructed of a brick outer wall, and an inner wall: 24 inches/8 inches thick, respectively. There is an air space between walls of . The tower has in place a Fourth Order Fresnel lens .〔(Terry Pepper, "Seeing the Light," History of Tawas Point Light. )〕〔(Buoy 2- Tawas Bay, Michigan )〕 The light can be seen for , and has a lens focal plane above Lake Huron’s average water level. The Keeper’s House is long and wide.〔(A Child's View of the Tawas Point Light, Michigan Time Traveler: Lansing State Journal. )〕 It is currently being remodeled by the Michigan Department of Natural Resources, with the assistance and contributions of the Friends of Tawas Point State Park. The downstairs eventually will become a museum for the lighthouse and the upstairs becoming a mini-cabin available for rent by the public. The house is itself available for one and two week stays (for a fee, and with an agreement to act as a trained volunteer).〔(Kart, Jess, ''Tawas Point Lighthouse looks for boarders willing to pay for privilege of living in working structure'', June 4, 2008. ) The Bay City Times.〕 Volunteer keepers will stay for up to two weeks. Because of its popularity, picturesque form and location, it is often the subject of photographs, and even of needlepoint illustrations.〔(Needlepoint of Tawas Point Light. )〕 The Tawas lifesaving station has recently been saved and renovation continues.〔(Michigan Lighthouse Conservancy, Tawas Lifesaving Station. )〕 The Fresnel lens is still operative, being one of Only 70 such lenses that remain operational in the United States, sixteen of which are use on the Great Lakes of which eight are in Michigan.〔(United States Coast Guard, Fresnel Lenses Still in Operation ).〕 In October 2015, the Coast Guard announced that it would remove the Fresnel lens and replace it with a modern optic beacon. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tawas Point Light」の詳細全文を読む スポンサード リンク
