Dufferin Island
Dufferin Island is an island on the Central Coast of British Columbia, Canada, on the south side of Seaforth Channel just northwest of Bella Bella. It was named in 1876 by Captain Chatfield and the officers of HMS Amethyst after Frederick Hamilton-Temple-Blackwood. Dufferin Island is part of a volcanic area called the Milbanke Sound Group which includes several monogenetic cinder cones. Holocene basalt Basalt (; ) is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of a ...ic lava flows from Dufferin Island overlie adjacent beach deposits. References Islands of British Columbia Central Coast of British Columbia {{BritishColumbiaCoast-geo-stub ...

Island
An island or isle is a piece of subcontinental land completely surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges Delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental islands and oceanic islands. There are also artificial islands (man-made islands). There are about 900,000 official islands in the world. This number consists of all the officially-reported islands of each country. The total number of islands in the world is unknown. There may be hundreds of thousands of tiny islands that are unknown and uncounted. The number of sea islands in the world is estimated to be more than 200,000. ...

Bella Bella, British Columbia
Bella Bella, also known as Waglisla, is the home of the Heiltsuk and is an unincorporated community and Indian reserve community located within Bella Bella Indian Reserve No. 1 on the east coast of Campbell Island in the Central Coast region of British Columbia, Canada. Bella Bella is located north of Port Hardy, on Vancouver Island, and west of Bella Coola. The community is on Lama Passage, part of the Inside Passage – a transportation route linking the area, and northern British Columbia as well as Alaska for marine vessels carrying cargo, passengers and recreational boaters from the south coast. The settlement "forms a national capital of sorts" to the Heiltsuk.'' Founded between 1897 and 1903, Bella Bella is located on Campbell Island. Originally styled New Bella Bella to distinguish it from "Bella Bella", the community's official post office name for some time was Waglisla, meaning "river on the beach" in the Heiltsuk language.

Captain Chatfield
Captain is a title, an appellative for the commanding officer of a military unit; the supreme leader of a navy ship, merchant ship, aeroplane, spacecraft, or other vessel; or the commander of a port, fire or police department, election precinct, etc. In militaries, the captain is typically at the level of an officer commanding a company or battalion of infantry, a ship, or a battery of artillery, or another distinct unit. The term also may be used as an informal or honorary title for persons in similar commanding roles. Etymology The term "captain" derives from (, , or 'the topmost'), which was used as title for a senior Byzantine military rank and office. The word was Latinized as capetanus/catepan, and its meaning seems to have merged with that of the late Latin "capitaneus" (which derives from the classical Latin word "caput", meaning head). This hybridized term gave rise to the English language term captain and its equivalents in other languages (, , , , , , , , , kapitány, K ...

HMS Amethyst (1873)
HMS ''Amethyst'' was the lead ship of the s built for the Royal Navy in the early 1870s. She participated in the Third Anglo-Ashanti War in 1873 before serving as the senior officer's ship for the South American side of the South Atlantic. The ship was transferred to the Pacific Station in 1875 and fought in the Battle of Pacocha against the rebellious Peruvian ironclad warship two years later. This made her the only British wooden sailing ship ever to fight an armoured opponent. After a lengthy refit, ''Amethyst'' again served as the senior officer's ship on the South American station from 1882 to 1885. She was sold for scrap two years later. Design and description ''Amethyst'' was long between perpendiculars, had a beam of and had a draught of . The ship displaced and had a burthen of 1,405 tons. Her crew consisted of 225 officers and ratings.Lyon & Winfield, p. 288 Unlike her iron-hulled contemporaries, the ship's wooden hull prevented any use of watertight transverse bu ...

Frederick Hamilton-Temple-Blackwood, 1st Marquess Of Dufferin And Ava
Frederick Temple Hamilton-Temple-Blackwood, 1st Marquess of Dufferin and Ava (21 June 182612 February 1902) was a British public servant and prominent member of Victorian society. In his youth he was a popular figure in the court of Queen Victoria, and became well known to the public after publishing a best-selling account of his travels in the North Atlantic. He is now best known as one of the most successful diplomats of his time. His long career in public service began as a commissioner to Syria in 1860, where his skilful diplomacy maintained British interests while preventing France from instituting a client state in Lebanon. After his success in Syria, Dufferin served in the Government of the United Kingdom as the Chancellor of the Duchy of Lancaster and Under- Secretary of State for War. In 1872 he became Governor General of Canada, bolstering imperial ties in the early years of the Dominion, and in 1884 he reached the pinnacle of his diplomatic career as Viceroy of Ind ...

Milbanke Sound Group
The Milbanke Sound Group, also called the Milbanke Sound Cones, is an enigmatic group of five small basaltic volcanoes in the Kitimat Ranges of the Coast Mountains in British Columbia, Canada. Named for Milbanke Sound, this volcanic group straddles on at least four small islands (three of which are uninhabited), including Swindle, Price, Lady Douglas and Lake Island. Not much is known about this group of volcanoes and they remain undated. However, they all likely formed in the past 10,000 years after the last glacial period as evidenced by a small amount of erosion. The age of the most recent volcanic activity is also unknown. Most of the Milbanke Sound Cones are covered by mature forest. Kitasu Hill and Helmet Peak are the only two cones that are officially named. This group of volcanoes is unlike many other volcanic groups in Canada as it resides on islands instead of on the mainland. The volcanoes form a northwest-southeast trend along the British Columbia Coast. To the west ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monogenetic Volcanic Field
A monogenetic volcanic field is a type of volcanic field consisting of a group of small monogenetic volcanoes, each of which erupts only once, as opposed to polygenetic volcanoes, which erupt repeatedly over a period of time. The small monogenetic volcanoes of these fields are the most common subaerial volcanic landform. Many monogenetic volcanoes are cinder cones, often with lava flows, such as Parícutin in the Michoacán-Guanajuato volcanic field, which erupted from 1943 to 1952. Some monogenetic volcanoes are small lava shields, such as Rangitoto Island in the Auckland volcanic field. Other monogenetic volcanoes are tuff rings or maars. A monogenetic field typically contains between ten and a hundred volcanoes. The Michoacán-Guanajuato field in Mexico contains more than a thousand volcanoes and is exceptionally large. Monogenetic fields occur only where the magma supply to the volcano is low or where vents are not close enough or large enough to develop plumbing system ...

Cinder Cone
A cinder cone (or scoria cone) is a steep conical hill A conical hill (also cone or conical mountain) is a landform with a distinctly conical shape. It is usually isolated or rises above other surrounding foothills, and is often of volcanic origin. Conical hills or mountains occur in different shap ... of loose pyroclastic fragments, such as volcanic clinkers, volcanic ash, or scoria that has been built around a volcanic vent. The pyroclastic fragments are formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as either cinders, clinkers, or scoria around the vent to form a cone that often is symmetrical; with slopes between 30 and 40°; and a nearly circular ground plan. Most cinder cones have a bowl-shaped Volcanic crater, crater at the summit. Mechanics of eruption Cinder cones range in size from tens to hundreds of meter ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
