A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny . Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics . Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets .

40-556: The Australian Alps are a mountain range in southeast Australia . The range comprises an interim Australian bioregion , and is the highest mountain range in Australia. The range straddles the borders of eastern Victoria , southeastern New South Wales , and the Australian Capital Territory . It contains Australia's only peaks exceeding 2,000 m (6,600 ft) in elevation, and is the only bioregion on

80-508: A bushfire. Statewide, the fires burned out over 400,000 hectares and destroyed 2,029 properties. Within the Australian Alps, the roughly 120 active alpine huts mostly date back to the early cattlemen's days, early skiing huts, and early research and surveying huts. Many of these have remained in use by fly fishers (seasonal), hikers , and skiing groups throughout the year. Most of these huts are maintained by volunteers through

120-526: A means of reproduction, and fire events are an interwoven and an essential part of the ecology of the continent. In some eucalypt and banksia species, for example, fire causes seed pods to open, allowing them to germinate. Fire also encourages the growth of new grassland plants. Other species have adapted to recover quickly from fire. Nevertheless, damage to surrounding human habitations and native fauna can be extensive and occasionally catastrophic. The 2003 Canberra bushfires severely affected almost 70% of

160-460: A shorter ski was worn on the other foot for kicking. The underside of the short ski was either plain or covered with animal skin to aid this use, while the long ski supporting the weight of the skier was treated with animal fat in a similar manner to modern ski waxing . Early skiers used one long pole or spear. The first description of a skier with two ski poles dates to 1741. Troops in continental Europe were equipped with skis by 1747. Skiing

200-538: 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

240-513: Is found at Thredbo and Australia's biggest resort, Perisher is now found. The State of Victoria is the one with the largest number of skiing areas in Australia. Mount Bogong , with its peak at 1986 m above sea level, is the highest peak in Victoria. The surrounding Bogong High Plains is one of the largest areas of snow country in Australia. It includes the leading resorts of Falls Creek and Mount Hotham . Recreational and practical skiing

280-474: Is practiced in certain areas that are reserved exclusively for ski jumping. Telemark skiing is a ski turning technique and FIS-sanctioned discipline, which is named after the Telemark region of Norway. It uses equipment similar to Nordic skiing, where the ski bindings are attached only at the toes of the ski boots, allowing the skier's heel to be raised throughout the turn. However, the skis themselves are often

320-689: Is protected by large national parks , in particular the Kosciuszko National Park in New South Wales and the adjoining Alpine National Park in Victoria. These are managed cooperatively as the Australian Alps National Parks by agencies of the Australian government and the state governments of this region. The Australian Alps also contain the only skiing areas of mainland Australia. Along with

360-670: Is the use of skis to glide on snow for basic transport, a recreational activity, or a competitive winter sport . Many types of competitive skiing events are recognized by the International Olympic Committee (IOC), and the International Ski and Snowboard Federation (FIS). Skiing has a history of almost five millennia. Although modern skiing has evolved from beginnings in Scandinavia , it may have been practiced more than 100 centuries ago in

400-865: 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 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

440-521: The Altai Mountains , according to an interpretation of ancient paintings. However, this continues to be debated. The word "ski" comes from the Old Norse word "skíð" which means to "split piece of wood or firewood". Asymmetrical skis were used in northern Finland and Sweden until at least the late 19th century. On one foot, the skier wore a long straight non-arching ski for sliding, and

480-551: The Annamite Range . If the definition of a mountain range is stretched to include underwater mountains, then 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

520-804: 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 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

560-692: The Kosciuszko Huts Association and the local National Parks and Wildlife Service. Some of the more noteworthy huts include Moscow Villa Hut , Valentine Hut, Seaman's Hut , and Mawsons Hut. In recent years many huts have been lost through lack of maintenance and bush fire, as occurred with the Pretty Plain Hut and Mount Franklin Chalet , which were destroyed by the Canberra bushfires of 2003. The Australian Alps are

600-554: 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 . Skiing Skiing

640-427: The Australian Alps and gregariously aestivates in caves and other sites throughout the mountain range during the summer to avoid high temperatures and lack of larval food resources. The moth is a food source for many species living within the region, such as the endangered mountain pygmy possum . However, the moth has also been a biovector of arsenic , transporting it from lowland feeding sites over long distances into

680-419: The Australian Alps is Mount Kosciuszko (2,228 metres (7,310 ft)). Formation of the Australian Alps was largely complete by around 100 million years ago, but during the past 90 million years, a number of minor uplift episodes have occurred, with occasional eruptions of basalt lava from small volcanoes, which has flowed across the landscape and down some of the valleys, filling in the low-lying areas to form

720-480: The Australian Alps were not formed by two continental plates colliding and pushing up the Earth's rocky mantle to form jagged, rocky peaks. Instead, the Australian Alps consist of a high plateau, with significantly softer rolling hills spread across a long, wide plateau that was lifted thousands of feet up by the movement of magma when Gondwana began to break up between 130 and 160 million years ago. The highest peak in

760-565: The Australian Alps. There are approximately 40 native mammals, 200 bird species, 30 reptile species, 15 amphibians, 14 native fish species, and a wide variety of invertebrates. Additionally, many non-native, feral species have been introduced to the Alps, such as the European rabbit, deer, house mice, red foxes, dogs, cats, horses, and pigs. Among this wide variety of different species of wildlife, there are different habitat requirements for each of

800-775: The Australian Capital Territory's pasture, forests (pine plantations), and nature parks. After burning for a week through the Brindabella Ranges above Canberra, the fires entered the suburbs of the city on 18 January 2003. Four people died and more than 500 homes were destroyed or severely damaged. The Victorian Black Saturday bushfires were particularly intense in parts of the Victorian High Country and destroyed several towns, including Kinglake and Marysville . The fires killed 173 people, Australia's highest-ever loss of life from

840-614: The Australian Capital Territory; and the Victorian Alps , located in Victoria. The latter region is also known as the "High Country", particularly within a cultural or historical context. Unlike the high mountain ranges found in places like the Rockies (highest peak 4,401 m (14,439 ft)), the European Alps (highest peak 4,808 m (15,774 ft)) or the Himalayas (highest peak 8,848 m (29,029 ft)),

880-545: The Australian mainland in which deep snow falls annually . The range comprises an area of 1,232,981 ha (3,046,760 acres). The Australian Alps are part of the Great Dividing Range , the series of mountain and hill ranges and tablelands that runs about 3,000 km (1,900 mi) from northern Queensland , through New South Wales, and into the northern part of Victoria. This chain of highlands divides

920-627: The air descends on the leeward side, it warms again (following the adiabatic lapse rate ) and 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

960-471: The bottom of alpine skis to give them traction on snow. This permits Nordic style uphill and back-country travel on alpine skis. For downhill travel, the heels are locked and the skins are removed. The Nordic disciplines include cross-country skiing and ski jumping , which both use bindings that attach at the toes of the skier's boots but not at the heels. Cross-country skiing may be practiced on groomed trails or in undeveloped backcountry areas. Ski jumping

1000-753: The drainage of the rivers that flow to the east into the Pacific Ocean from those that flow west into the drainage of the Murray–Darling Basin (and thence to the Southern Ocean ) or into inland waters, such as Lake Eyre , which lie below sea level, or else evaporate rapidly. The Australian Alps consist of two biogeographic sub regions: the Snowy Mountains , including the Brindabella Range , located in New South Wales and

1040-485: 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,

1080-461: The flat landscapes of these high plains. During the Pleistocene ice age, commencing around 2 million years ago, when ice caps formed on many high ranges around the world, as well as at the poles, small glaciers were formed on the very highest parts of the Australian Alps, mostly in the vicinity of Mount Kosciuszko. Whilst no glaciers remain today, evidence of their past presence can be found in

1120-594: The idea to the frozen hills around the town. The first and longest-surviving ski club in the world, the Kiandra Snow Shoe Club , is believed to have been formed at Kiandra in that year. Steeper slopes and more reliable snows lie further to the south, and in the 20th century the focus of recreational skiing in New South Wales shifted southward, to mountains in and around the Kosciuszko Main Range region, where Australia's best vertical drop

1160-466: The main region in which skiing in Australia takes place (although skiing is also possible in Tasmania ). Skiable terrain stretches through large areas of territory from June to October. New South Wales is home to Australia's highest snow country, oldest ski fields, and largest resort. Recreational skiing in Australia began around 1861 at Kiandra , New South Wales, when Norwegian gold miners introduced

1200-639: The mentioned species, regardless of whether it is native or introduced. In addition to rock outcrops and decaying logs, there is often vegetation that provides food and shelter or a combination of these factors. Consequently, topography, soil type, and temperature determine the type of vegetation in an area and how animal populations are distributed. The Australian Alps have been classified by BirdLife International as an Important Bird Area . The range's montane forests and woodlands support large breeding populations of flame robins and pilotbirds . The bogong moth seasonally migrates long distances towards and from

1240-772: The mountains, leading to the bioaccumulation of the element in the environment and animals in the mountain range. Due to their mostly hot, dry climate, bushfires in Australia occur frequently, particularly in the well-forested areas of the Australian Alps. The Alps, particularly on the Victorian side of the border (known as the Victorian Alps), are periodically subject to major bushfires and have been almost entirely burnt through by bushfires on various occasions, notably; Black Thursday in 1851 , Black Friday (1939) , and during fires in 2003 and 2006-07 . Certain native flora in Australia have evolved to rely on bushfires as

1280-653: The numerous tarns and cirques found in that region, such as Club Lake, Blue Lake, and Hedley Tarn. The Australian Alps are important for conservation , recreation , and as a water drainage basin , with much of the range's eastern slopes having its runoff diverted artificially into the Murray River and its tributary the Murrumbidgee River through the civil engineering project of the Snowy Mountains Scheme . The range's natural ecology

1320-627: 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

1360-479: 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 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

1400-543: The same width as Alpine skis. The following skiing disciplines are sanctioned by the FIS . Many have their own world cups and are included in the Winter Olympic Games . Equipment used in skiing includes: Technique has evolved along with ski technology and ski geometry . Early techniques included the telemark turn, the stem , the stem Christie , snowplough , and parallel turn . New parabolic designs like

1440-478: The supervision of the ski patrol and the ski school . Alpine skiing branched off from the older Nordic type of skiing around the 1920s when the advent of ski lifts meant that it was no longer necessary to climb back uphill. Alpine equipment has specialized to the point where it can now only be used with the help of lifts. Alpine Touring setups use specialized bindings which are switchable between locked and free-heel modes. Climbing skins are temporarily attached to

1480-682: The town of Cabramurra, New South Wales , these are practically the only permanent settlements in the area. Several medium-sized towns can be found in the valleys below the foothills, such as Jindabyne, New South Wales , Corryong, Victoria , and Mount Beauty . The Australian Alps are not as high or as steep as the European Alps, New Zealand's Southern Alps , or the Andes Mountains , and most of their peaks can be reached without using mountaineering equipment. Hundreds of species of mammals, birds, reptiles, amphibians, and fish live in

1520-548: The two is the type of ski binding (the way in which the ski boots are attached to the skis). Also called "downhill skiing", Alpine skiing typically takes place on a piste at a ski resort . It is characterized by fixed-heel bindings that attach at both the toe and the heel of the skier's boot. Ski lifts , including chairlifts , bring skiers up the slope. Backcountry skiing can be accessed by helicopter , snowcat , hiking and snowmobile . Facilities at resorts can include night skiing , après-ski , and glade skiing under

1560-660: Was being practised in the Victorian Alps by the 1880s and 1890s with skis made from local timbers, and making use of single steering poles. Skiing began at Mount Buffalo in the 1890s, and a chalet was constructed in 1910. Australia's first ski tow was constructed near Mount Buffalo in 1936. Cross-country skiing is possible in the ACT, as well as in New South Wales and Victoria, but downhill skiing can only be done in New South Wales and Victoria: Mountain range Mountain ranges are usually segmented by highlands or mountain passes and valleys . Individual mountains within

1600-504: Was primarily used for transport until the mid-19th century but, since then, it has also become a recreation and sport. Military ski races were held in Norway during the 18th century, and ski warfare was studied in the late 18th century. As equipment evolved and ski lifts were developed during the late 19th and early 20th centuries, two main genres of skiing emerged— Alpine (downhill) skiing and Nordic skiing . The main difference between
