Milwaukee Pierhead Light
The Milwaukee Pierhead Light is an active lighthouse located in the Milwaukee, Wisconsin, Milwaukee harbor, just south of downtown. This aid to navigation is a 'sister' of the Kenosha North Pier Light. History The station was established in 1872. It is west of the Milwaukee Breakwater Light, and is near the outflow of the Milwaukee River—not far east of where that river converged with the Kinnickinnic River (Milwaukee River), Kinnickinnic River—into the Milwaukee Harbor and Lake Michigan. This light has a round steel tower with a round Balcony, gallery and a ten-sided lantern. In 1926, the original 4th Order Fresnel lens was transferred to the Milwaukee Breakwater Light, and that lens is now displayed at the Wisconsin Maritime Museum in Manitowoc, Wisconsin. The Fifth Order Fresnel lens—installed in 1926—was removed in 2005. The tower is newly painted circa 2007. The 5th Order lens is said to be on display also at the Wisconsin Maritime Museum.National Park Service]Mariti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frustum
In geometry, a (from the Latin for "morsel"; plural: ''frusta'' or ''frustums'') is the portion of a solid (normally a pyramid or a cone) that lies between two parallel planes cutting this solid. In the case of a pyramid, the base faces are polygonal, the side faces are trapezoidal. A right frustum is a right pyramid or a right cone truncated perpendicularly to its axis; otherwise it is an oblique frustum. If all its edges are forced to become of the same length, then a frustum becomes a prism (possibly oblique or/and with irregular bases). In computer graphics, the viewing frustum is the three-dimensional region which is visible on the screen. It is formed by a clipped pyramid; in particular, ''frustum culling'' is a method of hidden surface determination. In the aerospace industry, a frustum is the fairing between two stages of a multistage rocket (such as the Saturn V), which is shaped like a truncated cone.

According to the 2020 census, Manitowoc had a population of 34,626, with over 50,000 residents in the surrounding communities.

Lighthouse Digest
''Lighthouse Digest'', a specialty magazine from FogHorn Publishing in East Machias, Maine, is about maritime history with particular attention to the preservation of lighthouses and their past. Though it is geared toward enthusiasts and antiquarians in the United States, it is also quoted commonly in more academic publications, and its editors have become a staple presence in scholarly circles. Editor Tim Harrison issued the first number in May, 1992. Scope Coverage includes historic and current lighthouse events and an events calendar for lighthouse activities around the United States and elsewhere. They publish a "Doomsday List" of Endangered lighthouses, and have helped save a number of at-risk lighthouses. They have been credited with uncovering many parts of lighthouse history that had been unknown, or which were thought to have been lost. Each issue carries articles and unusual lighthouse-related stories that, for the most part, cannot be found elsewhere, and many phot ...

Interstate 43
Interstate 43 (I-43) is a Interstate Highway located entirely within the US state of Wisconsin, connecting I-39/ I-90 in Beloit with Milwaukee and I-41, U.S. Highway 41 (US 41) and US 141 in Green Bay. State Trunk Highway 32 (WIS 32) runs concurrently with I-43 in two sections and I-94, I-894, US 10, US 41, US 45, and WIS 57 overlap I-43 once each. There are no auxiliary or business routes connected to I-43, though an alternate route to direct traffic during road closures is signed along local and state highways from Milwaukee County north into Brown County. I-43 came about as a result of toll road proposals that included a Milwaukee to Superior corridor that included Hurley, Wausau, and Green Bay. Only the Milwaukee-to-Green Bay section was approved. The route was originally planned to follow an alignment about midway between US 41 and US 141 (the latter paralleled Lake Michigan at the time) along WIS ...

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] |
Lighthouse Keeper
A lighthouse keeper or lightkeeper is a person responsible for tending and caring for a lighthouse, particularly the light and lens in the days when oil lamps and clockwork mechanisms were used. Lighthouse keepers were sometimes referred to as "wickies" because of their job trimming the wicks. Duties and functions Historically, lighthouse keepers were needed to trim the wicks, replenish fuel, wind clockworks and perform maintenance tasks such as cleaning lenses and windows. They were also responsible for the fog signal and the weather station, and played a major role in search and rescue at sea. Because most lighthouses are located in remote, isolated or inaccessible areas on islands and coastlines, it was typical for the work of lighthouse keeper to remain within a family, passing from parents to child, all of whom lived in or near the lighthouse itself. "Stag light" was an unofficial term given to some isolated lighthouses in the United States Lighthouse Service. It meant sta ...
