Erie Land Light
The Erie Land Light, also known as the Old Presque Isle Light, is a lighthouse on the shore of Lake Erie in Erie, Pennsylvania. It is one of the three lighthouses in Erie, along with the Presque Isle Light and the North Pier Light. The lighthouse is situated on the bluffs overlooking the lake in Lighthouse Park east of downtown Erie. The lighthouse was originally constructed in 1818 becoming one of the first to be built by the United States on the Great Lakes. The tower was replaced in 1851 for the first time; in 1858, due to its poor foundations and soil quality, it sank into the ground. The current structure was built in 1867 and remained in service until 1880. It was reactivated five years later before being permanently decommissioned in 1899. Both the lenses and lantern were eventually removed. The Erie Land Light was sold to the city of Erie in 1934 and was documented by the Historic American Buildings Survey (HABS) in 1936. It was listed on the National Register of Historic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Lighthouse
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] |
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] |

Buffalo Main Light
Buffalo (Main) Light is a lighthouse at the mouth of Buffalo River/Erie Canal, directly across from the Erie Basin Marina in Buffalo, New York. History The lighthouse was established and lit in 1833 and was deactivated in 1914. The foundation material was stone molehead and the lighthouse was constructed out of limestone and cast iron. The shape of the tower was octagonal and was high. The lens installed in 1857 was a third order Fresnel lens. The lens was later removed to the Buffalo History Museum. ''Note:'' This includes This 60-foot-tall, octagonal limestone structure is the oldest still standing in its original location in the city of Buffalo. It replaced the original 1818 light on this site along the Lake Erie shore at the mouth of the Buffalo River.

United States Statutes At Large
The ''United States Statutes at Large'', commonly referred to as the ''Statutes at Large'' and abbreviated Stat., are an official record of Acts of Congress and concurrent resolutions passed by the United States Congress. Each act and resolution of Congress is originally published as a slip law, which is classified as either public law (abbreviated Pub.L.) or private law (Pvt.L.), and designated and numbered accordingly. At the end of a Congressional session, the statutes enacted during that session are compiled into bound books, known as "session law" publications. The session law publication for U.S. Federal statutes is called the ''United States Statutes at Large''. In that publication, the public laws and private laws are numbered and organized in chronological order. U.S. Federal statutes are published in a three-part process, consisting of slip laws, session laws (''Statutes at Large''), and codification ('' United States Code''). Codification Large portions of public l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Presque Isle State Park
Presque Isle State Park () is a Pennsylvania State Park on an arching, sandy peninsula that juts into Lake Erie, west of the city of Erie, in Millcreek Township, Erie County, Pennsylvania, in the United States. The peninsula sweeps northeastward, surrounding Presque Isle Bay along the park's southern coast. It has of roads, of recreational trails, 13 beaches for swimming, and a marina. Popular activities at the park include swimming, boating, hiking, biking, and birdwatching. The recorded history of Presque Isle begins with the Erielhonan, a Native American tribe who gave their name to Lake Erie, and includes French, British, and American forts, as well as serving as a base for Commodore Oliver Hazard Perry's fleet in the War of 1812. With the growing importance of shipping on Lake Erie in the 19th century, Presque Isle became home to several lighthouses and what later became a United States Coast Guard station.

Buffalo River (New York)
The Buffalo River drains a watershed in Western New York state, emptying into the eastern end of Lake Erie at the Buffalo, New York, City of Buffalo. The river has three tributaries: Cayuga Creek, Buffalo Creek, and Cazenovia Creek. The Buffalo River has been important to the development of western New York, including as the terminus for the Erie Canal beginning in 1825, and later as an industrial area with uses including grain elevators, steel mills and chemical production. When shipping began to bypass the Erie Canal in the 1950s, and later heavy industry declined, the transportation and industrial uses of the river were greatly reduced. Many adjacent factories and grain mills were abandoned. The river and adjacent sites have been the focus of efforts over several decades to improve water quality and restore habitat, most recently in 2011 with the commencement of the Buffalo River Restoration Project.

Height Above Mean Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects suc ...

Focal Plane
In Gaussian optics, the cardinal points consist of three pairs of points located on the optical axis of a rotationally symmetric, focal, optical system. These are the '' focal points'', the principal points, and the nodal points. For ''ideal'' systems, the basic imaging properties such as image size, location, and orientation are completely determined by the locations of the cardinal points; in fact only four points are necessary: the focal points and either the principal or nodal points. The only ideal system that has been achieved in practice is the plane mirror, however the cardinal points are widely used to ''approximate'' the behavior of real optical systems. Cardinal points provide a way to analytically simplify a system with many components, allowing the imaging characteristics of the system to be approximately determined with simple calculations. Explanation The cardinal points lie on the optical axis of the optical system. Each point is defined by the effect the opti ...
