Hallett Cove Conservation Park is a protected area located in Hallett Cove, South Australia on the shore of Gulf St Vincent, south of the Adelaide city centre. Hallett Cove is one of the best known geological sites in Australia and is known for its international significance. The area has been declared a Geological Monument by the Geological Society of Australia and placed on the South Australian Heritage Register for its educational and scientific significance. ==History== Hallett Cove is named for John Hallett who discovered the area while searching for lost stock in 1837. In the 1840s the cove was used by smugglers to land goods at night which were then taken to Adelaide by dray. In 1847, the Worthing Mining Company purchased from the Hallett family and built a copper mine on the northern side of Hallett's creek. However, the ground proved to be too hard and water kept flooding the diggings. In 1852 the miners left for the Victorian gold rush and the mine was finally abandoned in 1857. Farming began in what is now the eastern section of the park in the 1850s. In the late 1880s the cove was used for naval exercises and the southern area of beach was cleared of rocks to allow landings.〔 Professor Ralph Tate realised that South Australia had been subjected to an ice age when in 1877 he discovered the area's smoothed and striated glacial pavement. In 1893, "the largest scientific excursion ever held in the Southern Hemisphere" explored the area with Prof. Walter Howchin later demonstrating that the deposits were of Permian age and that Australia was closer to the south pole than today while part of the Gondwanan supercontinent. During that time the south-western two-thirds of Australia, including much of South Australia was covered by an ice sheet. The first detailed description of the geology of the area was published in 1943.〔 In 1957 Professor A.R. Alderman from the University of Adelaide wrote to the National Trust of South Australia recommending that the glacial pavements along the coastal cliff tops of Hallett Cove be preserved. In 1960, local farmer George Sandison died and the beneficiaries of his estate donated of land, a narrow strip along the cliff tops, to the National Trust of South Australia which was followed not long after by another for an access road. In 1965 the donated land was proclaimed ''The Sandison Reserve''.〔 In 1965 subdivision of the adjacent land for housing was announced. For the next 11 years conservationists fought against developments. In late 1969, the State Planning Authority declared of Hallett Cove a site of scientific interest which prohibited landowners from developing the land in any way that would destroy its scientific value. In 1970 it was announced that the surrounding land would be subdivided and a large private marina built in the cove. The government received tens of thousands of letters of protest and significant public debate ensued. Premier Dunstan guaranteed to protect the area and the government later acquired the cove and a further of land.〔 In 1976, the park was declared a Conservation Park dedicated for the protection of features of geological and historic interest. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hallett Cove Conservation Park」の詳細全文を読む スポンサード リンク
