Context: The Grand Island East Channel Light is a lighthouse located just north of Munising, Michigan and was intended to lead boats from Lake Superior through the channel east of Grand Island into the Munising Harbor. Constructed of wood, the light first opened for service in 1868. The light was very hard to see from Lake Superior, and light maintenance was very difficult so the Munising Range Lights were constructed (Munising Rear Range Light, Munising Front Range Light) and this light was removed from service in 1908 or 1913 (sources vary)., Munising is a city on the southern shore of Lake Superior on the Upper Peninsula of the U.S. state of Michigan. The population was 2,355 at the 2010 census. It is the county seat of Alger County. The city is adjacent to the northwest corner of Munising Township, but is administratively autonomous., The Munising Rear Range Light works with the Munising Front Range Light to project a line of light out into Lake Superior in order to guide boats from the open lake into the safe harbor at Munising, Michigan. This harbor is a natural bay (thus providing protection from easterly or westerly storms) and sheltered on the north by Grand Island. Grand Island however provides a serious navigation hazard, and as boats navigate in the East Channel, there are several dangerous rock ledges that will sink the unwary captain. This pair of range lights replaced the ineffective Grand Island East Channel Light in 1905. The history of these lighthouses is documented by Terry Pepper and is not reproduced here., A lighthouse is a tower, building, or other type of structure designed to emit light from a system of lamps and lenses, and to serve as a navigational aid for maritime pilots at sea or on inland waterways., The Munising Front Range Light and its matching Munising Rear Range Light replaced the ineffective Grand Island East Channel Light in 1905 . These two lights combine to guide boats from the open waters of Lake Superior down the East Channel next to Grand Island into the harbor of Munising . The history of these lighthouses is documented by Terry Pepper and is not reproduced here . The Front Range Light is located at the western edge of Munising north of M - 28 . At this time , the light is managed by the National Park Service , the grounds are open to visitors , but the tower is closed . According to US Government publication , `` The American Practical Navigator '' , Chapter 5 : Range lights are light pairs that indicate a specific line of position when they are in line . The higher rear light is placed behind the front light . When the mariner sees the lights vertically in line , he is on the range line . If the front light appears left of the rear light , the observer is to the right of the range line ; if the front appears to the right of the rear , the observer is left of the range line ., Lake Superior is the largest of the Great Lakes of North America. The lake is shared by the Canadian province of Ontario to the north, the US state of Minnesota to the west, and Wisconsin and Michigan to the south. It is generally considered the largest freshwater lake in the world by surface area. It is the world's third-largest freshwater lake by volume and the largest by volume in North America., Subject: munising front range light, Relation: located_in_the_administrative_territorial_entity, Options: (A) alger county (B) east (C) freshwater (D) grand island (E) michigan (F) north (G) of (H) south (I) superior (J) west (K) westerly (L) wisconsin
