Egg Rock Light (Maine)
Egg Rock Light is a lighthouse on Frenchman Bay, Maine. Built in 1875, it is one of coastal Maine's architecturally unique lighthouses, with a square tower projecting through the square keeper's house. Located on Egg Rock, midway between Mount Desert Island and the Schoodic Peninsula, it is an active aid to navigation, flashing red every 40 seconds. The light was listed on the National Register of Historic Places as Egg Rock Light Station in 1988. Description and history The Egg Rock Light Station consists of two buildings, a combination light tower and keeper's house, and a fog station building. The keeper's house is a roughly square -story wood-frame building, with a hip roof pierced by dormers on all four sides. The painted brick tower, high, rises through the center of the house. The light is a VRB-25 aerobeacon, mounted in a 1986 replacement lantern house. It is configured to flash red every 40 seconds. The fog station is a brick structure southwest of the main buildin ...

Nahant, Massachusetts
Nahant is a town in Essex County, Massachusetts, United States. The population was 3,334 at the 2020 census, which makes it the smallest municipality by population in Essex County. With just of land area, it is the smallest municipality by area in the state. It is primarily a residential community. The town is situated on peninsula consisting of two near-islands (known as "Little Nahant" and "Big Nahant" respectively) connected to the mainland by a narrow sandy isthmus traversed by a single causeway known as "Nahant Road". Numerous tourist beaches line the shores, with the most popular being the so-called "Long Beach" and "Short Beach" along the eastern side of the causeway. History The area around Nahant was inhabited for thousands of years prior to European colonization of the Americas, but little is known of this period until European records began to document the area in the early 1600s. At that time, the seat of "Sagamore James" of the Naumkeag, known in his own tongue ... [...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] |
Lighthouses In Hancock County, Maine
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] |

Egg Rock Light - Frenchman's Bay
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , the ostrich ...

Frenchman Bay
Frenchman Bay is a bay in Hancock County, Maine, named for Samuel de Champlain, the French explorer who visited the area in 1604. Frenchman Bay may have been the location of the Jesuit St. Sauveur mission, established in 1613. In a 1960 book titled, "The Story of Mount Desert Island", Samuel Eliot Morison wrote, "Frenchmans Bay was so called because it became a staging point for French warships preparing to fight the English." The bay is bounded on the east by the Schoodic Peninsula, and on the west by Mount Desert Island; parts of both are in Acadia National Park. It contains numerous islands, the largest of which is Ironbound Island. The highest elevation of the islands in the bay is found on Jordan Island. The largest town on the bay is Bar Harbor, on Mount Desert Island Mount Desert Island (MDI; french: Île des Monts Déserts) in Hancock County, Maine, is the largest island off the coast of Maine. With an area of it is the 52nd-largest island in the United States, ... [...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 and inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schoodic Peninsula
The Schoodic Peninsula is a peninsula in Down East Maine. It is located four miles (6 km) east of Bar Harbor, Maine, as the crow flies. The Schoodic Peninsula contains , or approximately 5% of Acadia National Park. It includes the towns of Gouldsboro and Winter Harbor. The peninsula has a rocky granite shoreline containing many volcanic dikes. The peninsula is home to the former United States Navy base, NSGA Winter Harbor, which has been converted into a National Park Service training center. A resort development was proposed for land abutting Schoodic Peninsula's national park holdings to the north. An anonymous donor eventually bought the entire 3,200-acre tract and built the Schoodic Woods Campground and miles of gravel bike paths before donating all of it to Acadia National Park. Opening in 2015, Schoodic Woods is the newest campground in Acadia National Park, and the first built in the park since the original campgrounds were built by the Civilian Conservation Co ...
