33-762: The Mount Lofty Ranges are a range of mountains in the Australian state of South Australia which for a small part of its length borders the east of Adelaide . The part of the range in the vicinity of Adelaide is called the Adelaide Hills and defines the eastern border of the Adelaide Plains . The Mount Lofty Ranges stretch from the southernmost point of the Fleurieu Peninsula at Cape Jervis northwards for over 300 kilometres (190 mi) before petering out north of Peterborough . In

66-531: A number of endemic orchids. Similar habitats can be found on the offshore Kangaroo Island which is included by the World Wildlife Fund in the Mount Lofty woodlands ecoregion . The mountains are home to a number of marsupials such as the koala , western gray kangaroo , southern brown bandicoot along with the egg laying echidna . Birds include the southern emu-wren which is endemic to

99-410: A single railway crosses the ranges: the major Adelaide to Melbourne railway line , which was first constructed in the 1870s and has had only minor realignments since (the most significant of which was the boring of a new tunnel at Sleeps Hill). Passenger services used to run from the city to Bridgewater in the heart of the hills and ranges, but now stop at Belair in the foothills. A railway approached

132-493: A threat to habitats and wildlife. Protected areas tend to be small and fragmented. Mountain range Mountain ranges are usually segmented by highlands or mountain passes and valleys . Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology . They may be a mix of different orogenic expressions and terranes , for example thrust sheets , uplifted blocks , fold mountains, and volcanic landforms resulting in

165-476: A valuable source for the production of superphosphate fertilisers vital for the postwar development of the State's outlying agricultural areas. The runoff from the mine unfortunately proved quite toxic for the local environment, and efforts have been underway since to alleviate the damage. A small short-lived silver and lead mine in the foothills of the ranges at Glen Osmond was first opened just two years after

198-843: A variety of rock types . Most geologically young mountain ranges on the Earth's land surface are associated with either the Pacific Ring of Fire or the Alpide belt . The Pacific Ring of Fire includes the Andes of South America, extends through the North American Cordillera , the Aleutian Range , on through Kamchatka Peninsula , Japan , Taiwan , the Philippines , Papua New Guinea , to New Zealand . The Andes

231-445: A wide variety of land usage, including significant residential development, particularly concentrated in the foothills, suburbs of Stirling and Bridgewater , and the towns Mount Barker and Victor Harbor in particular. Several pine plantation forests exist, most significantly around Mount Crawford and Cudlee Creek in the north and Kuitpo Forest and Second Valley in the south. Several protected areas exist near Adelaide where

264-722: Is 7,000 kilometres (4,350 mi) long and is often considered the world's longest mountain system. The Alpide belt stretches 15,000 km across southern Eurasia , from Java in Maritime Southeast Asia to the Iberian Peninsula in Western Europe , including the ranges of the Himalayas , Karakoram , Hindu Kush , Alborz , Caucasus , and the Alps . The Himalayas contain the highest mountains in

297-520: Is a small town in the Adelaide Hills located 34 kilometres (21 mi) south-east of Adelaide in South Australia . The area was settled by Europeans during the period of British colonisation of South Australia in 1839, with the town laid out in 1849. The name of the town was derived from a name takes its name from the Kaurna word Ityangga , meaning "over there" or "close by". Gold

330-552: Is also home to the only conservation park in the northern ranges, Spring Gully . The northern end of the ranges are home to two curiosities: a tiny township by the name of Yongala , familiar to South Australians for commonly being the coldest place in the state (being a hundred kilometres inland, and on a somewhat elevated plateau as with much of the Mid North). The other curiosity is a locality near Orroroo called "Magnetic Hill". The name stems from an optical illusion that creates

363-538: Is at work while the mountains are being uplifted until the mountains are reduced to low hills and plains. The early Cenozoic uplift of the Rocky Mountains of Colorado provides an example. As the uplift was occurring some 10,000 feet (3,000 m) of mostly Mesozoic sedimentary strata were removed by erosion over the core of the mountain range and spread as sand and clays across the Great Plains to

396-531: Is drier, having been stripped of much of its moisture. Often, a rain shadow will affect the leeward side of a range. As a consequence, large mountain ranges, such as the Andes, compartmentalize continents into distinct climate regions . Mountain ranges are constantly subjected to erosional forces which work to tear them down. The basins adjacent to an eroding mountain range are then filled with sediments that are buried and turned into sedimentary rock . Erosion

429-627: The Mithrim Montes and Doom Mons on Titan, and Tenzing Montes and Hillary Montes on Pluto. Some terrestrial planets other than Earth also exhibit rocky mountain ranges, such as Maxwell Montes on Venus taller than any on Earth and Tartarus Montes on Mars . Jupiter's moon Io has mountain ranges formed from tectonic processes including the Boösaule , Dorian, Hi'iaka and Euboea Montes . Echunga, South Australia Echunga ( / ɪ ˈ tʃ ʌ ŋ ɡ ə / ih- CHUNG -gə )

462-540: The Murray River . The ranges form part of the water supply for Adelaide, and there is an extensive infrastructure of reservoirs, weirs, and pipelines, on the Torrens , Onkaparinga , Little Para and Gawler River catchments. Mount Bold , South Para , Kangaroo Creek , and Millbrook reservoirs are the largest. The northern ranges, often confused with the southern Flinders Ranges , and sometimes referred to as

495-473: The Ocean Ridge forms the longest continuous mountain system on Earth, with a length of 65,000 kilometres (40,400 mi). The position of mountain ranges influences climate, such as rain or snow. When air masses move up and over mountains, the air cools, producing orographic precipitation (rain or snow). As the air descends on the leeward side, it warms again (following the adiabatic lapse rate ) and

528-554: The Skilly Hills . Mining, although totally absent today, was once a major industry in the northern ranges. The copper mine at Kapunda, just north of the Barossa, operated from 1842 to 1877 and was a major boost to the infant State's economy, but was soon overshadowed by the large workings at Burra , further north. The mine here operated from 1845 to 1877 with a few minor interruptions, and was superseded by even larger workings on

561-519: The Yorke Peninsula . As testament to the volume of copper at Burra, however, the mine re-opened as an open-cut in 1971, before closing again ten years later. The Clare Valley lies in a shallow fold of the northern Mount Lofty Ranges just southwest of Burra. It is yet another world-class wine-producing area, and is a very popular weekend tourist destination for people living in Adelaide . It

594-623: The "Mid-North ranges" or "central hill country", stretch from hills near Kapunda in the south to arid ranges beyond Peterborough in the northeast. The highest peak in this section (and in all the Mount Lofty Ranges – despite the name) is Mount Bryan (936 m or 3,071 ft). Other significant peaks include New Campbell Hill (714 m or 2,343 ft) and Stein Hill (605 m or 1,985 ft), which overlooks Burra . The northern ranges include Belvidere Range , Tothill Range and

627-523: The Adelaide region, trending northeast to southwest defining these blocks: All the fault zones are still active today, along with the rest of the ranges, and minor earthquakes are relatively common. Larger quakes in the southern ranges are fairly rare: the last to hit a major centre was the 1954 Adelaide earthquake that occurred on 1 March. It measured 5.5 on the Richter scale . A significant aspect of

660-928: The Fleurieu Peninsula. There are a number of reptiles including the endangered Adelaide pygmy blue-tongue skink . Biodiversity losses have been severe in the ranges due to the clearance of temperate woodlands. The hillsides have largely been cleared of woodland for fruit growing and other agriculture and the urban growth of Adelaide particularly on the lower slopes, leading to loss of habitat and local extinction of wildlife species including all species of bettong and quoll marsupials and birds including regent honeyeater ( Xanthomyza phrygia ), swift parrot ( Lathamus discolor ), king quail ( Coturnix chinensis ), brown quail ( C. ypsilophora ), and azure kingfisher ( Alcedo azurea ). Clearance and agriculture are ongoing and livestock grazing continues to cause damage to habitats while introduced cats, foxes and rabbits are

693-485: The east. This mass of rock was removed as the range was actively undergoing uplift. The removal of such a mass from the core of the range most likely caused further uplift as the region adjusted isostatically in response to the removed weight. Rivers are traditionally believed to be the principal cause of mountain range erosion, by cutting into bedrock and transporting sediment. Computer simulation has shown that as mountain belts change from tectonically active to inactive,

726-534: The founding of the State in 1836: it is significant for being not only the first metal mine in the history of the State, but the first in all Australia. South Australia never experienced a nineteenth-century gold rush like those interstate, but gold was mined near both Echunga and Williamstown (in the Barossa). Other mines in the southern ranges include a nineteenth-century silver-lead mine at Talisker near Cape Jervis, which features many remaining old buildings, and

759-452: The geology of the Adelaide area is a number of Tertiary marine sands deposits, many of which have been extensively quarried. One of these deposits is around the outer-northern suburb of Golden Grove ; another area is around McLaren Vale . The natural habitat of the mountainsides is woodland of eucalyptus trees mixed with golden wattle acacia trees on the lower slopes, all with an undergrowth of shrubs and herbs. The flowers include

792-494: The hills face the city in order to preserve highly sought-after residential land: Black Hill Conservation Park , Cleland National Park and Belair National Park are the largest. The other significant parks in the southern ranges are Deep Creek National Park , on the rugged southern shores of the Fleurieu Peninsula, and Para Wirra Conservation Park at the southern edge of the Barossa Valley. There are many wineries in

825-543: The impression that a car rolls uphill. The ranges are part of the Adelaide Rift Complex . The southern ranges and slopes of Mount Lofty overlooking the Adelaide Plains have been block-faulted to form a half- graben structure. The ranges when viewed from the beach or city have a "stepped" appearance, reflected in an early name for the ranges, "The Tiers". There are several major normal faults in

858-465: The limestone mine at Rapid Bay , which ceased operations much more recently. Copper was mined at Kapunda , Truro and Kanmantoo and may be again [1] and a zinc (and lead, silver and gold) mine is proposed near Strathalbyn [2] . Quarries dot the ranges, the most spectacular and massive of which are in the Adelaide foothills; they supplied much of the quartzite which is to be seen in the enduring "sandstone architecture" of early Adelaide. Today, only

891-608: The northern ranges (400 millimetres (16 in)). The part of the ranges south of and including the Barossa Valley are commonly known as the South Mount Lofty Ranges, and the highest part of this section is the summit of Mount Lofty (710 m or 2,330 ft). The part of the ranges nearest Adelaide is called the Adelaide Hills and, further north, the Barossa Range . The ranges encompass

924-418: The ranges at Willunga (although it was closed and removed in the 1960s and has since been replaced by a cycling trail). The Victor Harbor railway line (now used only for recreational purposes) largely skirts the eastern edge of the ranges. North of Adelaide, there was a railway to Angaston in the east of the Barossa Valley, and former railways to Truro and across the ranges near Eudunda to Morgan on

957-541: The ranges. Two wine regions in particular are world-renowned: the Barossa Valley and McLaren Vale . Grapes are also grown in the Adelaide Hills and the Onkaparinga Valley. Although no major mines operate in the southern ranges today, there are several large disused ones, and a myriad of small ones. An iron sulfide mine at Brukunga , northeast of Mount Barker, operated from 1955 to 1972, proving

990-627: The rate of erosion drops because there are fewer abrasive particles in the water and fewer landslides. Mountains on other planets and natural satellites of the Solar System, including the Moon , are often isolated and formed mainly by processes such as impacts, though there are examples of mountain ranges (or "Montes") somewhat similar to those on Earth. Saturn 's moon Titan and Pluto , in particular, exhibit large mountain ranges in chains composed mainly of ices rather than rock. Examples include

1023-572: The vicinity of Adelaide, they separate the Adelaide Plains from the extensive plains that surround the Murray River and stretch eastwards to Victoria. The Heysen Trail traverses almost the entire length of the ranges, crossing westwards to the Flinders Ranges near Hallett . The mountains have a Mediterranean climate with moderate rainfall brought by south-westerly winds, hot summers and cool winters. The southern ranges are wetter (with 900 millimetres (35 in) of rain per year) than

1056-543: The world, including Mount Everest , which is 8,848 metres (29,029 ft) high. Mountain ranges outside these two systems include the Arctic Cordillera , Appalachians , Great Dividing Range , East Siberians , Altais , Scandinavians , Qinling , Western Ghats , Vindhyas , Byrrangas , and the Annamite Range . If the definition of a mountain range is stretched to include underwater mountains, then

1089-493: Was discovered in 1852 and Echunga became the first proclaimed goldfield in South Australia. This led to a gold rush ; however, it did not last long, with the diggings exhausted and all but abandoned within a year. Subsequent discoveries in 1853 and 1854 led to smaller and equally short-lived rushes. In 1868 more gold was discovered at nearby Jupiter Creek , which proved to be a much larger and long-lived field. For
