Mount Alcantara
Mount Alcantara is a mountain summit located in British Columbia, Canada. Description Mount Alcantara is the highest point in the Blue Range, a subrange of the Canadian Rockies. This remote peak is situated west of the Continental Divide and south-southeast of majestic Mount Assiniboine. Precipitation runoff from Alcantara drains into Alcantara and Aurora creeks which are both part of the Cross River watershed. Topographic relief is significant as the summit rises over 1,500 meters (4,920 feet) above Aurora Creek in two kilometers (1.2 mile). History Mount Alcantara was named in 1916 to remember the RMS ''Alcantara'', an ocean liner that was converted to an armed merchant cruiser and was sunk by the German raider ''Greif'' during the First World War. The mountain's toponym was officially adopted October 12, 1966, by the Geographical Names Board of Canada. The first ascent of the summit was made in 1929 by Kate (Katie) Gardiner with guide Walter Feuz. Geology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cross River (British Columbia)
The Cross River is a tributary of the Kootenay River in the Canadian province of British Columbia. It is part of the Columbia River basin, as the Kootenay River is tributary to the Columbia River. The history regarding this river and Whiteman's Pass across the Continental Divide begins with James Sinclair leading a party of Red River immigrants through the pass in 1841. They left Fort Garry (now the city of Winnipeg) in 1841 with 23 families, including a 75-year-old woman, with an aim to settle in the Oregon Country to reinforce British claims to the area. After a brief stop at Fort Edmonton, he was guided by Maskepetoon, the chief of the Wetaskiwin Cree, via Lake Minnewanka to the present site of Banff, Alberta where the Spray River joins with the Bow River and then south up the Spray River valley where the reservoir now lies. They trekked up the Spray River, then along a tributary, White Man's Creek, and across the Great Divide at White Man's Pass. In his book "The Place of B ...

Laramide Orogeny
The Laramide orogeny was a time period of mountain building in western North America, which started in the Late Cretaceous, 70 to 80 million years ago, and ended 35 to 55 million years ago. The exact duration and ages of beginning and end of the orogeny are in dispute. The Laramide orogeny occurred in a series of pulses, with quiescent phases intervening. The major feature that was created by this orogeny was deep-seated, thick-skinned deformation, with evidence of this orogeny found from Canada to northern Mexico, with the easternmost extent of the mountain-building represented by the Black Hills of South Dakota. The phenomenon is named for the Laramie Mountains of eastern Wyoming. The Laramide orogeny is sometimes confused with the Sevier orogeny, which partially overlapped in time and space. The orogeny is commonly attributed to events off the west coast of North America, where the Kula and Farallon Plates were sliding under the North American plate. Most hypotheses propos ...

Jurassic
The Jurassic ( ) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and is the only boundary between geological periods to remain formally undefined. By the beginning of the Jurassi ...

Precambrian
The Precambrian (or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons ( Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago ( Ga) to the beginning of the Cambrian Period, about million years ago ( Ma), when hard-shelled creatures first appeared in abundance. Overview Relatively little is known about the Precambrian, despite it making up roughly seven-eighths of the Earth's history, and what is known has largely been discovered from the 1960s onwards.

Sedimentary Rock
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Ascent
In mountaineering, a first ascent (abbreviated to FA in guide books) is the first successful, documented attainment of the top of a mountain or the first to follow a particular climbing route. First mountain ascents are notable because they entail genuine exploration, with greater risks, challenges and recognition than climbing a route pioneered by others. The person who performs the first ascent is called the first ascensionist. In free climbing, a first ascent (or first free ascent, abbreviated FFA) of a climbing route is the first successful, documented climb of a route without using equipment such as anchors or ropes for aiding progression or resting. History The details of the first ascents of even many prominent mountains are scanty or unknown; sometimes the only evidence of prior summiting is a cairn, artifacts, or inscriptions at the top. Today, first ascents are generally carefully recorded and usually mentioned in guidebooks. The term is also used when referri ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SMS Greif (1914)
SMS ''Greif'' was a German cargo steamship that was converted into a merchant raider for the Imperial German Navy. Construction and conversion Built as ''Guben'', she was a steel-hulled ship owned by the German-Australian Line (DADG), Hamburg. She was converted for naval service at Kaiserliche Werft Kiel in 1915 and commissioned as ''Greif'' on 23 January 1916. Service history ''Greif'' sailed from the Elbe port of Cuxhaven on 27 February 1916Poole (July 1975) pp. 52–57 under the command of ''Fregattenkapitän'' Rudolf Tietze (born 13 September 1874, previously was commander of the battleship ).Schmalenbach (1977) p.16 The Royal Navy had learned of ''Greif''s sailing and was waiting in the North Sea.Schmalenbach (1977) p.34 Action of 29 February 1916 ''Greif'' was disguised as the Norwegian ''Rena'' bound for Tønsberg, Norway, when intercepted by the armed merchant cruiser on the morning of 29 February 1916.

Merchant Raider
Merchant raiders are armed commerce raiding ships that disguise themselves as non-combatant merchant vessels. History Germany used several merchant raiders early in World War I (1914–1918), and again early in World War II (1939–1945). The captain of a German merchant raider, Felix von Luckner, used the sailing ship SMS ''Seeadler'' for his voyage (1916–1917). The Germans used a sailing ship at this stage of the war because coal-fired ships had limited access to fuel outside of territories held by the Central Powers due to international regulations concerning refueling of combat ships in neutral countries. Germany sent out two waves of six surface raiders each during World War II. Most of these vessels were in the range. Many of these vessels had originally been refrigerator ships, used to transport fresh food from the tropics. These vessels were faster than regular merchant vessels, which was important for a warship. They were armed with six 15 cm (5.9 inch) naval gu ...

Armed Merchantman
An armed merchantman is a merchant ship equipped with guns, usually for defensive purposes, either by design or after the fact. In the days of sail, piracy and privateers, many merchantmen would be routinely armed, especially those engaging in long distance and high value trade. In more modern times, auxiliary cruisers were used offensively as merchant raiders to disrupt trade chiefly during both World War I and World War II, particularly by Germany. While armed merchantmen are clearly inferior to purpose-built warships, sometimes they have scored successes in combat against them. Examples include East Indiamen mimicking ships of the line and chasing off regular French warships in the Battle of Pulo Aura in 1804, and the sinking the Australian light cruiser in their battle in 1941, although ''Kormoran'' was also destroyed and had to be scuttled. Pre-20th century East Indiamen of various European countries were heavily armed for their long journeys to the Far East. In pa ...
