Etymology Signal Hill was originally known as Los Cerritos (“The Little Hills") but got its current name when it became the signal point of the United States Coast and Geodetic Survey in 1889. History The hill that the city is named after is above the surrounding town of Long Beach. Because of this height, it was used by the local Tongva Indians for signal fires that could be seen throughout the surrounding area and even out to Catalina Island, away.

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and location information about more than two million physical and cultural features, encompassing the United States and its territories; the Compact of Free Association, associated states of the Marshall Islands, Federated States of Micronesia, and Palau; and Antarctica. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alta California
Alta California (, ), also known as Nueva California () among other names, was a province of New Spain formally established in 1804.

The territory included all of the present-day U.S. states of California, Nevada, and Utah, and parts of Arizona, Wyoming, and Colorado. The territory was with Baja California Territory, Baja California (as a single ) in Mexico's 1836 ''Siete Leyes'' (Seven Laws) constitutional reform, granting it more autonomy. That change was undone in 1846, but rendered moot by the outcome of the Mexican–American War in 1848, when most of the areas formerly comprising Alta California Mexican Cession, were ceded to the U.S. in Treaty of Guadalupe Hidalgo, the treaty which ended the war.

Smoke Signal
The smoke signal is one of the oldest forms of long-distance communication. It is a form of visual communication used over a long distance. In general smoke signals are used to transmit news, signal danger, or to gather people to a common area. History and usage In History of China#Ancient China, ancient China, soldiers along the Great Wall sent smoke signals on its beacon towers to warn one another of enemy invasion. The colour of the smoke communicated the size of the invading party. By placing the beacon towers at regular intervals, and situating a soldier in each tower, messages could be transmitted over the entire 7,300 kilometres of the Wall. Smoke signals also warned the inner castles of the invasion, allowing them to coordinate a defense and garrison supporting troops. Misuse of the smoke signal is traditionally considered to have contributed to the fall of the Western Zhou dynasty in the 8th century BCE. King You of Zhou was said to have had a habit of fooling his warl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Indians In The United States
Native Americans (also called American Indians, First Americans, or Indigenous Americans) are the Indigenous peoples of the United States, particularly of the lower 48 states and Alaska. They may also include any Americans whose origins lie in any of the indigenous peoples of North or South America. The United States Census Bureau publishes data about "American Indians and Alaska Natives", whom it defines as anyone "having origins in any of the original peoples of North and South America ... and who maintains tribal affiliation or community attachment". The census does not, however, enumerate "Native Americans" as such, noting that the latter term can encompass a broader set of groups, e.g. Native Hawaiians, which it tabulates separately. The European colonization of the Americas from 1492 resulted in a precipitous decline in the size of the Native American population because of newly introduced diseases, including weaponized diseases and biological warfare by colonizers,C ...

Tongva People
The Tongva ( ) are an Indigenous people of California from the Los Angeles Basin and the Southern Channel Islands, an area covering approximately . In the precolonial era, the people lived in as many as 100 villages and primarily identified by their village rather than by a pan-tribal name. During colonization, the Spanish referred to these people as Gabrieleño and Fernandeño, names derived from the Spanish missions built on their land: Mission San Gabriel Arcángel and Mission San Fernando Rey de España. ''Tongva'' is the most widely circulated endonym among the people, used by Narcisa Higuera in 1905 to refer to inhabitants in the vicinity of Mission San Gabriel. Some people who identify as direct lineal descendants of the people advocate the use of their ancestral name '' Kizh'' as an endonym. The Tongva, along with neighboring groups such as the Chumash, played an important role in the cultural and economic dynamics of the region at the time of European encounter. T ...

Signal Oil Field Aerial 1930
A signal is both the process and the result of transmission of data over some media accomplished by embedding some variation. Signals are important in multiple subject fields including signal processing, information theory and biology. In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers. The ''IEEE Transactions on Signal Processing'' includes audio, video, speech, image, sonar, and radar as examples of signals. A signal may also be defined as observable change in a quantity over space or time (a time series), even if it does not carry information. In nature, signals can be actions done by an organism to alert other organisms, ranging from the release of plant chemicals to warn nearby plants of a predator, to sounds or motions made by animals to alert other animals of food. Signaling occurs in all organisms even at cellular levels, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Coast And Geodetic Survey
The United States Coast and Geodetic Survey ( USC&GS; known as the Survey of the Coast from 1807 to 1836, and as the United States Coast Survey from 1836 until 1878) was the first scientific agency of the Federal government of the United States, United States Government.

Petroleum
Petroleum, also known as crude oil or simply oil, is a naturally occurring, yellowish-black liquid chemical mixture found in geological formations, consisting mainly of hydrocarbons. The term ''petroleum'' refers both to naturally occurring unprocessed crude oil, as well as to petroleum products that consist of refining, refined crude oil. Petroleum is a fossil fuel formed over millions of years from anaerobic decay of organic materials from buried prehistoric life, prehistoric organisms, particularly planktons and algae, and 70% of the world's oil deposits were formed during the Mesozoic. Conventional reserves of petroleum are primarily recovered by oil drilling, drilling, which is done after a study of the relevant structural geology, sedimentary basin analysis, analysis of the sedimentary basin, and reservoir characterization, characterization of the petroleum reservoir. There are also unconventional (oil & gas) reservoir, unconventional reserves such as oil sands and oil sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
