Monomoy Point Light
Monomoy Point Light is a historic light in Chatham, Massachusetts. The station was established in 1823. The first light was a wood tower and brick lantern room on top of the keeper's house. The current tower, one of the first made of cast iron, was built in 1849. After the opening of the Cape Cod Canal in 1914, most vessels bound from south of the Cape to the Boston area took the shorter and safer route through the canal, so there was much less traffic past the light and the light was deactivated in 1923. It was added to the National Register of Historic Places as Monomoy Point Lighthouse on November 1, 1979, reference number 79000324. The keeper's house is preserved and serves today as a guest house. The Lighthouse Preservation Society, the Massachusetts Audubon Society, and The Friends of Monomoy support preservation of the lighthouse and keeper's house. It lies within the Monomoy Wilderness.

Monomoy Island
Monomoy Island is an spit of sand extending southwest from Chatham, Cape Cod off the Massachusetts mainland. Because of shifting sands and water levels, it is often connected to the mainland, and at other times is separated from it. It is home to the Monomoy National Wildlife Refuge. It is referred to in the 1691 Massachusetts Charter as Cape Mallabar, also spelled Cape Malabar. History Despite its remoteness, Monomoy was home to its own community as early as 1710. A tavern for sailors was opened up in the location of today's Hospital Pond, known then as Wreck Cove. During the early 19th century, a deep natural harbor at Monomoy's inner shore known as the Powder Hole attracted a sizeable fishing settlement. In its prime, Whitewash Village housed about 200 residents, a tavern inn called Monomoit House, and Public School #13, which boasted 16 students at one time. Cod and mackerel brought in to the Monomoy port were dried and packed for markets in Boston and New York Ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Chatham, Massachusetts
Chatham () is a town in Barnstable County, Massachusetts, United States. Chatham is located at the southeast tip of Cape Cod and has historically been a fishing community. First settled by the English in 1664, the township was originally called Monomoit based on the indigenous population's term for the region. Chatham was incorporated as a town on June 11, 1712, and has become a summer resort area. The population was 6,594 at the 2020 census, and can swell to 25,000 during the summer months. There are four villages that comprise the town, those being Chatham (CDC), South Chatham, North Chatham, and West Chatham. Chatham is home to the Monomoy National Wildlife Refuge, and the decommissioned Monomoy Point Light both located on Monomoy Island. A popular attraction is the Chatham Light, which is an operational lighthouse that is operated by the United States Coast Guard.

Cast Iron
Cast iron is a class of iron– carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications a ...

Cape Cod Canal
The Cape Cod Canal is an artificial waterway in the U.S. state of Massachusetts connecting Cape Cod Bay in the north to Buzzards Bay in the south, and is part of the Atlantic Intracoastal Waterway. The approximately canal traverses the neck of land joining Cape Cod to the state's mainland. It mostly follows tidal rivers widened to and deepened to at mean low water, shaving off the journey around the Cape for its approximately 14,000 annual users. Most of the canal is located in the town of Bourne, but its northeastern terminus is in Sandwich. Scusset Beach State Reservation lies near the canal's north entrance, and the Massachusetts Maritime Academy is near its south. A swift-running current changes direction every six hours and can reach during the receding ebb tide. The waterway is maintained by the United States Army Corps of Engineers and has no toll fees. It is spanned by the Cape Cod Canal Railroad Bridge, the Bourne Bridge, and the Sagamore Bridge. Traffic lig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouse Preservation Society
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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Massachusetts Audubon Society
The Massachusetts Audubon Society, commonly known as Mass Audubon, founded in 1896 by Harriet Hemenway and Minna B. Hall and headquartered in Lincoln, Massachusetts, is a nonprofit organization dedicated to "protecting the nature of Massachusetts". Mass Audubon is independent of the National Audubon Society (NAS), and was founded earlier than the NAS. Mass Audubon protects more than 38,000 acres of land throughout Massachusetts, saving birds and other wildlife, and making nature accessible to all with its wildlife sanctuaries and 20 nature centers. History The Massachusetts Audubon Society was born out of Harriet Hemenway's desire to stop the commercial slaughter of birds for women's ornamental hats. Hemenway and her cousin, Minna Hall, soon enlisted 900 women and formed a partnership with many from Boston's scientific community to form their organization. They named the organization the Massachusetts Audubon Society in honor of the bird painter John James Audubon. In 1905, a nat ...

Monomoy Wilderness
The Monomoy Wilderness is a wilderness area south of Cape Cod in the U.S. state of Massachusetts. It is located within the Monomoy National Wildlife Refuge and is administered by the US Fish & Wildlife Service. Severe winter storms isolated Monomoy Point from the mainland in 1958 and, 20 years later, separated North Monomoy Island from South Monomoy Island. Sand dunes on the eastern shore of the islands give way to salt marsh and then to mudflats on the western shore. The ecosystem is a perfect habitat for migratory birds.Monomoy Wilderness - Wilderness.net Dubbed a sanctuary for wildlife in 1944, most of Monomoy National Wildlife Refuge has been designated wilderness. This includes the entire north island and all but two tracts on the south island. The mainland portion of the Refuge is not wi ...
