Mount Lyell, Tasmania
Mount Lyell is a mountain in the West Coast Range of Western Tasmania, Australia. Mount Lyell has an elevation of above sea level. The adjacent mountains are Mount Sedgwick to the north and Mount Owen to the south. The mountain was named by Charles Gould in 1863 after geologist Charles Lyell, a supporter of Charles Darwin. Mount Lyell was also the common short name of the Mount Lyell Mining and Railway Company. Mining activity The Mount Lyell company operations centred mainly on the shoulder between Mount Owen and Mount Lyell, and to the western side of the mountain. On the eastern side of the shoulder were the old North Mount Lyell workings, where the 1912 North Mount Lyell Disaster occurred. There was a small operation in the early days of the mining operation that was on the northern side of Mount Lyell, known as the Comstock mine. In the late twentieth century, just west of the Comstock workings was a section of the mine known as Cape Horn. The western end of the ...

Lake Margaret (Tasmania)
Lake Margaret is a concrete-faced gravity dam with an uncontrolled spillway across the Yolande River, located on the north side of Mount Sedgwick, in the West Coast Range, West Coast of Tasmania, Australia. The impounded reservoir is also called Lake Margaret. The dam was constructed in 1918 by the Mount Lyell Mining and Railway Company for the purpose of generating hydro-electric power via the Lake Margaret Power Station, which is located below the dam wall. Following the closure of the Mount Lyell Mining and Railway Company, in 1985 the control of the dam, lake, and power station was transferred to Hydro Tasmania. Features and location The dam, called Lake Margaret, was completed in 1918 and it was the first gravity dam constructed in Tasmania. It was built of concrete with conglomerate "plums". The dam wall is high and is long and the concrete-faced dam wall has a volume of . The uncontrolled spillway has a capacity of . In 1974 the dam wall was strengthened by the use ...

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English natural history#Before 1900, naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a Common descent, common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this Phylogenetics, branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by Burials and memorials in Westminster Abbey, burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh Medical School, ...

The Peaks Of Lyell
''The Peaks of Lyell'' is a book by Geoffrey Blainey, based on his University of Melbourne MA thesis originally published in 1954. It contains the history of the Mount Lyell Mining and Railway Company, and through association, Queenstown and further the West Coast Tasmania. It is unique for this type of book in that it has gone to the sixth edition in 2000, and few company histories in Australia have achieved such continual publishing. Blainey was fortunate in being able to speak to older people about the history of the West Coast, some who had known Queenstown in its earliest years. The book gives an interesting overview from the materials and people Blainey was able to access in the early 1950s, and the omissions. Due to the nature of a company history, a number of items of Queenstown history did have alternative interpretations on events such as the 1912 North Mount Lyell Disaster, and there were residents of Queenstown living in the town as late as the 1970s who had stor ...

Linda Valley, Tasmania
Linda Valley is a valley in the West Coast Range of Tasmania. It was earlier known as the Vale of Chamouni. It is located between Mount Owen and Mount Lyell. Human settlement Linda Valley is the location of two historical settlements, Linda and Gormanston. These settlements were close to the Mount Lyell mines and workings, at the western edge of Lake Burbury, and east of the old Mount Lyell Mining and Railway Company operations. The terminus of the North Mount Lyell Railway was at Gormanston for a short time, the main point of operations for the railway was the yard and railway station at Linda, known as the Linda Valley station in early records. A feature in the landscape is the formation created for the Comstock Tram that was proposed to circumnavigate Mount Lyell but was never completed; it started at Linda.

1912 North Mount Lyell Disaster
The North Mount Lyell disaster (also known as the Mount Lyell disaster and North Mount Lyell fire) refers to a fire that broke out on 12 October 1912 at the Mount Lyell Mining and Railway Company operations on the West Coast of Tasmania, killing 42 miners. The mine had been taken over from the North Mount Lyell Company in 1903. Events Sometime between 11:15 and 11:30 am on 12 October the pump house on the level of the mine was reported on fire. As the mine lacked an emergency warning system, those aware of the fire were forced to run along its levels and drives warning others. Of the 170 miners working in the mine, 73 managed to escape that first day. However many, including those who had been working in remote stopes, were trapped. Outside the mine, uncertainty surrounded the status of the fire and the number of miners remaining inside. Initial rescue attempts proved difficult, and repeated attempts to enter the mine failed. The rescue plan involved the transportation of b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Lyell Mining And Railway Company
Mount Lyell Mining and Railway Company was a Tasmanian mining company formed on 29 March 1893, most commonly referred to as ''Mount Lyell''. Mount Lyell was the dominant copper mining company of the West Coast from 1893 to 1994, and was based in Queenstown, Tasmania. Following consolidation of leases and company assets at the beginning of the twentieth century, Mount Lyell was the major company for the communities of Queenstown, Strahan and Gormanston. It remained dominant until its closure in 1994. The Mount Lyell mining operations produced more than a million tonnes of copper, 750 tonnes of silver and 45 tonnes of gold since mining commenced in the early 1890s – which is equivalent to over 4 billion dollars worth of metal in 1995 terms. History In the early stage of operations, Mount Lyell was surrounded by smaller competing leases and companies. Eventually they were all absorbed into Mount Lyell operations, or were closed down. In 1903 the North Mount Lyell Copper C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Lyell
Sir Charles Lyell, 1st Baronet, (14 November 1797 – 22 February 1875) was a Scottish geologist who demonstrated the power of known natural causes in explaining the earth's history. He is best known as the author of '' Principles of Geology'' (1830–33), which presented to a wide public audience the idea that the earth was shaped by the same natural processes still in operation today, operating at similar intensities. The philosopher William Whewell termed this gradualistic view " uniformitarianism" and contrasted it with catastrophism, which had been championed by Georges Cuvier and was better accepted in Europe. The combination of evidence and eloquence in ''Principles'' convinced a wide range of readers of the significance of "deep time" for understanding the earth and environment. Lyell's scientific contributions included a pioneering explanation of climate change, in which shifting boundaries between oceans and continents could be used to explain long-term variati ...
