Manistee Pierhead Lights
The Manistee Pierhead lights are a pair of active aids to navigation located on the north and south pier in the harbor of Manistee, Michigan, "Lake Michigan’s Victorian Port City." History The first light was on the south pier in 1870. Unfortunately, it burnt in the Great fire of 1871, October 8, 1871, along with the town of Manistee. Coincidentally, Manistee burnt on the same day as the Great Chicago Fire, Peshtigo Fire in Wisconsin, and fires in Port Huron and Holland, Michigan. Two lighthouses were built, one on each pier in 1875. Over the years the lights have been moved several times, including moves to and from the mainland, and to and from the south to the north pier. Lights have been torn down and rebuilt. The current tower is located on the north pier. It is constructed of cast iron, and was first listed in 1927. The tower is a white cylinder, and the keepers house is separate. The original lens was a Fifth Order Fresnel lens. The tower has also been rebuilt as ...

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The ''catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances. Description The Fresnel lens redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tourist Attractions In Manistee County, Michigan
Tourism is travel for pleasure or business; also the theory and practice of touring (other), touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tour (other), tours. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be Domestic tourism, domestic (within the traveller's own country) or International tourism, international, and international tourism has both incoming and outgoing implications on a country's balance of payments.

Lighthouses On The National Register Of Historic Places In Michigan
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Manistee County, Michigan
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lighthouses In The United States
This is a list of lighthouses in the United States. The United States has had approximately a thousand lights as well as light towers, range lights, and pier head lights. Michigan has the most lights of any state with over 150 past and present lights. Lighthouses that are in former U.S. territories are not listed here. Most of the lights in the United States have been built and maintained by the Coast Guard (since 1939) and its predecessors, the United States Lighthouse Service (1910–1939) and the United States Lighthouse Board (1852–1910). Before the Lighthouse Board was established, local collectors of customs were responsible for lighthouses under Stephen Pleasonton. As their importance to navigation has declined and as public interest in them has increased, the Coast Guard has been handing over ownership and in some cases responsibility for running them to other parties, the chief of them being the National Park Service under the National Historic Lighthouse Preservation ...

US 31
U.S. Route 31 or U.S. Highway 31 (US 31) is a major north–south U.S. highway connecting southern Alabama to northern Michigan. Its southern terminus is at an intersection with US 90/ US 98 in Spanish Fort, Alabama. Its northern terminus is at an interchange with Interstate 75 (I-75) south of Mackinaw City, Michigan. US 31 once crossed the Straits of Mackinac by car ferry to intersect US 2 north of St. Ignace, Michigan, in the Upper Peninsula and then formerly reached Mackinaw City along the southern approaches of the Mackinac Bridge (which has been taken over by I-75). It also formerly entered downtown Mobile, Alabama, via a long bridge over Mobile Bay. The southern segment of US 31 connects the cities of Mobile, Montgomery, Birmingham, and Decatur in Alabama, and Nashville in Tennessee.

National Historic Lighthouse Preservation Act
The National Historic Lighthouse Preservation Act of 2000 (NHLPA; Public Law 106-355; 16 U.S.C. 470w-7) is American legislation creating a process for the transfer of federally owned lighthouses into private hands. It was created as an extension of the National Historic Preservation Act of 1966. Background Maintenance of aids to navigation had been assigned to the federal government from the beginning, first under the Department of the Treasury, and then under the U.S. Lighthouse Board (1852-1910) and its successor, the U.S. Lighthouse Service. In 1939 lighthouses were placed under the authority of the United States Coast Guard, which also took over the manning of lights with keepers. Throughout this period the expense of maintaining and staffing lights was constantly stressed. Automation of lights began early in the twentieth century, and a major push in the early 1960s relieved all but a few lighthouses of their keepers. Lighthouses are fairly high maintenance structures, being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diaphone
The diaphone is a noisemaking device best known for its use as a foghorn: It can produce deep, powerful tones, able to carry a long distance. Although they have fallen out of favor, diaphones were also used at some fire stations and in other situations where a loud, audible signal was required. History The diaphone horn was based directly on the organ stop of the same name invented by Robert Hope-Jones, creator of the Wurlitzer organ. Hope-Jones' design was based on a piston that was closed only at its bottom end and had slots, perpendicular to its axis, cut through its sides; the slotted piston moved within a similarly slotted cylinder. Outside of the cylinder was a reservoir of high-pressure air. Initially, high-pressure air would be admitted behind the piston, pushing it forward. When the slots of the piston aligned with those of the cylinder, air passed into the piston, making a sound and pushing the piston back to its starting position, whence the cycle would repeat. A ...
