Marsh Lake
Marsh Lake (Mud Lake) is a widening of the Yukon River southeast of Whitehorse, Yukon, Canada. It is over 30 kilometres long and ranges from three to four kilometres wide. The co-ordinates of the lake are , and is 2,147 feet above sea level. The lake forms part of a chain of finger lakes, sometimes referred to as "The Southern Lakes", that form the headwaters of the Yukon River. The community of Marsh Lake, Yukon is located along the northern shores of the lake. History During the Klondike Gold Rush the Yukon River system was heavily relied upon for transportation. The passes and railhead to the southeast left the prospectors at Lake Bennett, the early ones had to build their own boats and float down the windy and dangerous Lake Bennett, Tagish Lake and "Mud Lake" before beginning on the Yukon River. A network of steamboats were soon developed and they began ferrying passengers to the rapids at Canyon City just outside what is now Whitehorse. These steamboats needed firewood ...

Yukon
Yukon (; ; formerly called Yukon Territory and also referred to as the Yukon) is the smallest and westernmost of Canada's three territories. It also is the second-least populated province or territory in Canada, with a population of 43,964 as of March 2022. Whitehorse, the territorial capital, is the largest settlement in any of the three territories. Yukon was split from the North-West Territories in 1898 as the Yukon Territory. The federal government's ''Yukon Act'', which received royal assent on March 27, 2002, established Yukon as the territory's official name, though ''Yukon Territory'' is also still popular in usage and Canada Post continues to use the territory's internationally approved postal abbreviation of ''YT''. In 2021, territorial government policy was changed so that “''The'' Yukon” would be recommended for use in official territorial government materials. Though officially bilingual (English and French), the Yukon government also recognizes First Natio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crystal Palace, Yukon
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The word ''crystal'' derives from the Ancient Greek word (), meaning both "ice" and "rock crystal", from (), "icy cold, frost". Examples of large crystals include snowflakes, diamonds, and table salt. Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. Polycrystals include most metals, rocks, ceramics, and ice. A third category of sol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fool's Gold
The mineral pyrite (), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Fe S2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of ''fool's gold''. The color has also led to the nicknames ''brass'', ''brazzle'', and ''Brazil'', primarily used to refer to pyrite found in coal. The name ''pyrite'' is derived from the Greek (), 'stone or mineral which strikes fire', in turn from (), 'fire'. In ancient Roman times, this name was applied to several types of stone that would create sparks when struck against steel; Pliny the Elder described one of them as being brassy, almost certainly a reference to what we now call pyrite. By Georgius Agricola's time, , the term had become a generic term for all of the sulfide minerals. Pyrite is usually found associated with other sulfides or oxides in quartz v ...

Judas Creek
Judas Iscariot (; grc-x-biblical, Ἰούδας Ἰσκαριώτης; syc, ܝܗܘܕܐ ܣܟܪܝܘܛܐ; died AD) was a disciple and one of the original Twelve Apostles of Jesus Christ. According to all four canonical gospels, Judas betrayed Jesus to the Sanhedrin in the Garden of Gethsemane by kissing him on the cheek and addressing him as "master" to reveal his identity in the darkness to the crowd who had come to arrest him. His name is often used synonymously with betrayal or treason. The Gospel of Mark gives no motive for Judas's betrayal, but does present Jesus predicting it at the Last Supper, an event also described in all the other gospels. The Gospel of Matthew states that Judas committed the betrayal in exchange for thirty pieces of silver. The Gospel of Luke and the Gospel of John suggest that he was possessed by Satan. According to , after learning that Jesus was to be crucified, Judas attempted to return the money he had been paid for his betrayal to the ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Othniel Charles Marsh
Othniel Charles Marsh (October 29, 1831 – March 18, 1899) was an American professor of Paleontology in Yale College and President of the National Academy of Sciences. He was one of the preeminent scientists in the field of paleontology. Among his legacies are the discovery or description of dozens of new species and theories on the origins of birds. Born into a modest family, Marsh was able to afford higher education thanks to the generosity of his wealthy uncle George Peabody. After graduating from Yale College in 1860 he travelled the world, studying anatomy, mineralogy and geology. He obtained a teaching position at Yale upon his return. From the 1870s to 1890s, he competed with rival paleontologist Edward Drinker Cope in a period of frenzied Western American expeditions known as the Bone Wars. Marsh's greatest legacy is the collection of Mesozoic reptiles, Cretaceous birds, and Mesozoic and Tertiary mammals that now constitute the backbone of the collections of Yale's Peabo ...

Frederick Schwatka
Frederick Gustavus Schwatka (29 September 1849 – 2 November 1892) was a United States Army lieutenant with degrees in medicine and law, and was a noted explorer of northern Canada and Alaska. Early life and career Schwatka was born in Galena, Illinois, the son of Frederick Gustavus Sr. and Amelia (Hukill) Schwatka. His father Frederick G. Sr. (1810-1888) was born in Baltimore, Maryland, the son of August and Catherine (Geissendorfer) Schwatke (the original German spelling with the same pronunciation), German Lutheran immigrants from East Prussia (now eastern Poland) and Bavaria, respectively. His mother Amelia Hukill (1812-1885) was born near Bethany, Brooke County, in present-day West Virginia and was of English and Scots descent. When he was 10 his family moved to Salem, Oregon. Schwatka later worked in Oregon as a printer's apprentice and attended Willamette University. He was appointed to the United States Military Academy at West Point in 1867 and graduated in 1871, se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canyon City, Yukon
Canyon City is a Klondike Gold Rush ghost town and a Yukon Government Heritage Site. It is located about 7 km from downtown Whitehorse, Yukon at the upstream end of Miles Canyon on the Yukon River. Summer tours are encouraged. Archaeological work shows evidence that First Nations people have used this area for many thousands of years. There were seasonal fish camps above and below Miles Canyon and the Whitehorse Rapids. Early explorers had little contact with the indigenous population, although Frederick Schwatka, in 1883, made note of a First Nations portage trail bypassing Miles Canyon, and, in 1887, George Mercer Dawson, noted the large number of salmon above the canyon — salmon were one of the fish that were important to the aboriginal population. 1898 The Gold Rush During the Klondike Gold Rush, the thousands of stampeders travelling down the Yukon River to Dawson, Miles Canyon and the Whitehorse Rapids were the most treacherous obstacles on the entire route.

Yukon River
The Yukon River (Gwichʼin language, Gwich'in: ''Ųųg Han'' or ''Yuk Han'', Central Alaskan Yup'ik language, Yup'ik: ''Kuigpak'', Inupiaq language, Inupiaq: ''Kuukpak'', Deg Xinag language, Deg Xinag: ''Yeqin'', Hän language, Hän: ''Tth'echù'' or ''Chuu k'onn'', Southern Tutchone: Chu Nìikwän, russian: Юкон, Yukon) is a major watercourse of northwestern North America. From its source in British Columbia, Canada, it flows through Canada's territory of Yukon (itself named after the river). The lower half of the river continues westwards through the U.S. state of Alaska. The river is long and empties into the Bering Sea at the Yukon–Kuskokwim Delta. The average flow is . The total drainage area is , of which lies in Canada. The total area is more than 25% larger than Texas or Alberta. The longest river in Alaska and Yukon, it was one of the principal means of transportation during the 1896–1903 Klondike Gold Rush. A portion of the river in Yukon—"The Thirty Mile" se ...

Steamboats
A steamboat is a boat that is marine propulsion, propelled primarily by marine steam engine, steam power, typically driving propellers or Paddle steamer, paddlewheels. Steamboats sometimes use the ship prefix, prefix designation SS, S.S. or S/S (for 'Screw Steamer') or PS (for 'Paddle Steamer'); however, these designations are most often used for steamships. The term ''steamboat'' is used to refer to smaller, insular, steam-powered boats working on lakes and rivers, particularly riverboats. As using steam became more reliable, steam power became applied to larger, ocean-going vessels. Background Limitations of the Newcomen steam engine Early steamboat designs used Newcomen atmospheric engine, Newcomen steam engines. These engines were large, heavy, and produced little power, which resulted in an unfavorable power-to-weight ratio. The Newcomen engine also produced a reciprocating or rocking motion because it was designed for pumping. The piston stroke was caused by a water jet i ...
