Trigg Island
Trigg Island is a small "island" off the coast of the suburb of Trigg in Perth, Western Australia. It is named after Henry Stirling Trigg, Superintendent of Public Works in the Colony of Western Australia from 1838 to 1851. Trigg Island is a small rocky aeolianite limestone remnant of Pleistocene dunes, better characterised as an outcrop than an island, and as such is typical of the Perth coast. It is sometimes physically joined to the beach by movements of both the sand and the tide. Trigg Island is notorious for its blue hole, located at the south end of the island. In September 1931, four men nearly died when their boat capsized near the blue hole. In May 1947, two brothers died in the blue hole, and later that year in July a nun named Sister Mary Chrysostom, and her would-be rescuer Frederick Charles Floyd, also drowned. A plaque commemorating the deaths of the latter two is stored in the Trigg Island Surf Life Saving Club facilities. Many others have been rescued or died ...

Perth
Perth is the capital and largest city of the Australian state of Western Australia. It is the fourth most populous city in Australia and Oceania, with a population of 2.1 million (80% of the state) living in Greater Perth in 2020. Perth is part of the South West Land Division of Western Australia, with most of the metropolitan area on the Swan Coastal Plain between the Indian Ocean and the Darling Scarp. The city has expanded outward from the original British settlements on the Swan River, upon which the city's central business district and port of Fremantle are situated. Perth is located on the traditional lands of the Whadjuk Noongar people, where Aboriginal Australians have lived for at least 45,000 years. Captain James Stirling founded Perth in 1829 as the administrative centre of the Swan River Colony. It was named after the city of Perth in Scotland, due to the influence of Stirling's patron Sir George Murray, who had connections with the area. It gained city statu ...

Henry Trigg
Henry Trigg (1791–1882) was the Superintendent of Public Works in Western Australia from 1839 to 1851 and founder of the Congregational Church in Perth. Biography Henry Trigg was born on 30 June 1791 in Gloucester, England, the son of Henry and Mary Trigg. In 1813 he married Amelia Ralph (b. 1791) and they had seven children, Eliza, Harriet, Emma, Jane, Amelia, Henry and William, prior to him leaving England. Trigg was a carpenter and a businessman but due to the economic depression in England following the Battle of Waterloo he felt that his family would have a better chance in the colonies and decided to emigrate to the Swan River Colony, leaving his family until he was set up and could afford their passage. At the age of 38, he emigrated to Western Australia, arriving on the in October 1829. His personal wealth (£200) allowed him to take up a land grant of in the colony. Trigg's grant encompasses what is now the suburb of Churchlands. In 1831, Amelia and their seven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colony Of Western Australia
In modern parlance, a colony is a territory subject to a form of foreign rule. Though dominated by the foreign colonizers, colonies remain separate from the administration of the original country of the colonizers, the '' metropolitan state'' (or "mother country"). This administrative colonial separation makes colonies neither incorporated territories nor client states. Some colonies have been organized either as dependent territories that are not sufficiently self-governed, or as self-governed colonies controlled by colonial settlers. The term colony originates from the ancient Roman '' colonia'', a type of Roman settlement. Derived from ''colon-us'' (farmer, cultivator, planter, or settler), it carries with it the sense of 'farm' and 'landed estate'. Furthermore the term was used to refer to the older Greek ''apoikia'' (), which were overseas settlements by ancient Greek city-states. The city that founded such a settlement became known as its ''metropolis'' ("mother-city ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeolianite
Eolianite or aeolianite is any rock formed by the lithification of sediment deposited by aeolian processes; that is, the wind. In common use, however, the term refers specifically to the most common form of eolianite: coastal limestone consisting of carbonate sediment of shallow marine biogenic origin, formed into coastal dunes by the wind, and subsequently lithified.

Description Sayles coined the term in 1931, when he described the dune-shaped hills of Bermuda, consisting of bioclastic grainstones. Thus, Bermuda is considered the type locality for carbonate eolianite facies, with clearly defined cross-bedding, foresets, and topsets. Deposition ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ''ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented sa ...

Blue Hole
A blue hole is a large marine cavern or sinkhole, which is open to the surface and has developed in a bank or island composed of a carbonate bedrock (limestone or coral reef). Their existence was discovered in the late 20th century by fishermen and recreational divers. Blue holes typically contain tidally influenced water of fresh, marine, or mixed chemistry. They extend below sea level for most of their depth and may provide access to submerged cave passages. Well-known examples are the Dragon Hole (in the South China Sea) and, in the Caribbean, the Great Blue Hole and Dean's Blue Hole. ''Blue holes'' are distinguished from ''cenotes'' in that the latter are inland voids usually containing fresh groundwater rather than seawater. Description Blue holes are roughly circular, steep-walled depressions, and so named for the dramatic contrast between the dark blue, deep waters of their depths and the lighter blue of the shallows around them. Their water circulation is poor, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
