56-684: Cradle Mountain is a locality and mountain in the Central Highlands region of the Australian state of Tasmania . The mountain is situated in the Cradle Mountain-Lake St Clair National Park . At 1,545 metres (5,069 ft) above sea level , it is the sixth-highest mountain in Tasmania . The locality of Cradle Mountain is a rural locality in the local government areas of Meander Valley , Kentish and West Coast in

112-741: A Subpolar oceanic climate ( Cfc ) with cool summers and cold, very snowy winters; with heavy precipitation throughout the year. Climate data are sourced from an altitude of 903 metres (2,963 ft) on the exposed western slopes. It receives an average of 47.9 snowy days annually, which occurs in every month of the year. The mountain rises above the glacially formed Dove Lake (934 metres [3,064 ft]), Lake Wilks and Crater Lake. The mountain has four named summits. In order of height they are Cradle Mountain (1,545 m [5,069 ft]), Smithies Peak (1,527 m [5,010 ft]), Weindorfers Tower (1,459 metres [4,787 ft]) and Little Horn (1,355 m [4,446 ft]). The mountain itself

168-428: A biotemperature below 1.5 °C (34.7 °F). Mountain environments are particularly sensitive to anthropogenic climate change and are currently undergoing alterations unprecedented in last 10,000 years. The effect of global warming on mountain regions (relative to lowlands) is still an active area of study. Observational studies show that highlands are warming faster than nearby lowlands, but when compared globally,

224-458: A mountain is roughly equivalent to moving 80 kilometres (45 miles or 0.75° of latitude ) towards the nearest pole. This relationship is only approximate, however, since local factors such as proximity to oceans (such as the Arctic Ocean) can drastically modify the climate. As the altitude increases, the main form of precipitation becomes snow and the winds increase. The effect of

280-466: A mountain, for the purposes of access, is a summit of 2,000 feet (610 m) or higher. In addition, some definitions also include a topographical prominence requirement, such as that the mountain rises 300 metres (984 ft) above the surrounding terrain. At one time, the United States Board on Geographic Names defined a mountain as being 1,000 feet (305 m) or taller, but has abandoned

336-471: A mountain. Elevation, volume, relief, steepness, spacing and continuity have been used as criteria for defining a mountain. In the Oxford English Dictionary a mountain is defined as "a natural elevation of the earth surface rising more or less abruptly from the surrounding level and attaining an altitude which, relatively to the adjacent elevation, is impressive or notable." Whether a landform

392-634: A significant role in religion. There are for example a number of sacred mountains within Greece such as Mount Olympus which was held to be the home of the gods. In Japanese culture, the 3,776.24 m (12,389.2 ft) volcano of Mount Fuji is also held to be sacred with tens of thousands of Japanese ascending it each year. Mount Kailash , in the Tibet Autonomous Region of China, is considered to be sacred in four religions: Hinduism, Bon , Buddhism, and Jainism . In Ireland, pilgrimages are made up

448-552: A vital part of Australia's biodiversity. Although Australia has national and state level biodiversity conservation strategies and has ratified international conventions, most overlook fungi, including Tasmania's Natural Heritage Strategy, which only makes one generic reference to fungi. One of the more a conspicuous species found in the wetter parts of the park is the strawberry bracket fungus ( Tyromyces pulcherrimus ). It grows on myrtle beech ( Nothofagus cunninghammii ) and snow gums. The Australian citizen-science organisation, Fungimap

504-495: A vital part of healthy ecosystems, regulating ecosystem functions. As primary recyclers of organic matter, saprobic fungi break down fallen branches and leaf litter , making vital nutrients available to other organisms. Other fungi form symbiotic relationships with other organisms. Although rarely acknowledged, the great majority of plants in Cradle Mountain-Lake St Clair National Park (and, indeed, in

560-467: A whole, 24% of the Earth's land mass is mountainous. There are three main types of mountains: volcanic , fold , and block . All three types are formed from plate tectonics : when portions of the Earth's crust move, crumple, and dive. Compressional forces, isostatic uplift and intrusion of igneous matter forces surface rock upward, creating a landform higher than the surrounding features. The height of

616-452: Is El Alto , Bolivia, at 4,150 metres (13,620 ft), which has a highly diverse service and manufacturing economy and a population of nearly 1 million. Traditional mountain societies rely on agriculture, with higher risk of crop failure than at lower elevations. Minerals often occur in mountains, with mining being an important component of the economics of some mountain-based societies. More recently, tourism has become more important to

672-515: Is 8,850 m (29,035 ft) above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m (69,459 ft). The tallest mountain including submarine terrain is Mauna Kea in Hawaii from its underwater base at 9,330 m (30,610 ft) and some scientists consider it to be the tallest on earth. There is no universally accepted definition of

728-492: Is a corrie lake near Cradle Mountain in the central highlands region of Tasmania , Australia . It lies in the Cradle Mountain-Lake St Clair National Park . The lake is a very popular visitor attraction and is encircled by well maintained walking paths which also lead up onto Cradle Mountain. It was named by prominent local Gustav Weindorfer after an official of the Van Diemen's Land Company . Like several other lakes in

784-478: Is a poor conductor of heat, so a parcel of air will rise and fall without exchanging heat. This is known as an adiabatic process , which has a characteristic pressure-temperature dependence. As the pressure gets lower, the temperature decreases. The rate of decrease of temperature with elevation is known as the adiabatic lapse rate , which is approximately 9.8 °C per kilometre (or 5.4 °F (3.0 °C) per 1000 feet) of altitude. The presence of water in

840-419: Is a set of outdoor activities that involves ascending mountains . Mountaineering-related activities include traditional outdoor climbing , skiing , and traversing via ferratas that have become sports in their own right. Indoor climbing , sport climbing , and bouldering are also considered variants of mountaineering by some, but are part of a wide group of mountain sports . Mountains often play

896-541: Is called a mountain may depend on local usage. John Whittow's Dictionary of Physical Geography states "Some authorities regard eminences above 600 metres (1,969 ft) as mountains, those below being referred to as hills." In the United Kingdom and the Republic of Ireland, a mountain is usually defined as any summit at least 2,000 feet (610 m) high, which accords with the official UK government's definition that

952-493: Is documenting and mapping the distribution of fungi including those that occur in national parks. Mountain A mountain is an elevated portion of the Earth's crust , generally with steep sides that show significant exposed bedrock . Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill , typically rising at least 300 metres (980  ft ) above

1008-540: Is named after its resemblance to a gold-mining cradle . The area is covered in a variety of alpine and sub-alpine vegetation, including the colourful deciduous beech , itself an anomaly given that most Australian native flora is evergreen. Alpine coral fern and button grass dominate the alpine wet sedgelands near the mountain summit. Stands of Tasmanian snow gum can be found at slightly lower elevations alongside Tasmanian eyebright , scoparia heath , mountain rocket , waratah , Cheshunt pine and pencil pine . Within

1064-556: Is not enough oxygen to support human life. This is sometimes referred to as the " death zone ". The summits of Mount Everest and K2 are in the death zone. Mountains are generally less preferable for human habitation than lowlands, because of harsh weather and little level ground suitable for agriculture . While 7% of the land area of Earth is above 2,500 metres (8,200 ft), only 140 million people live above that altitude and only 20-30 million people above 3,000 metres (9,800 ft) elevation. About half of mountain dwellers live in

1120-457: Is the highest mountain on Earth, at 8,848 metres (29,029 ft). There are at least 100 mountains with heights of over 7,200 metres (23,622 ft) above sea level, all of which are located in central and southern Asia. The highest mountains above sea level are generally not the highest above the surrounding terrain. There is no precise definition of surrounding base, but Denali , Mount Kilimanjaro and Nanga Parbat are possible candidates for

1176-525: Is the largest mountain on Earth in terms of base area (about 2,000 sq mi or 5,200 km ) and volume (about 18,000 cu mi or 75,000 km ). Mount Kilimanjaro is the largest non-shield volcano in terms of both base area (245 sq mi or 635 km ) and volume (1,150 cu mi or 4,793 km ). Mount Logan is the largest non-volcanic mountain in base area (120 sq mi or 311 km ). The highest mountains above sea level are also not those with peaks farthest from

1232-522: The Andes , Central Asia, and Africa. With limited access to infrastructure, only a handful of human communities exist above 4,000 metres (13,000 ft) of elevation. Many are small and have heavily specialized economies, often relying on industries such as agriculture, mining, and tourism. An example of such a specialized town is La Rinconada, Peru , a gold-mining town and the highest elevation human habitation at 5,100 metres (16,700 ft). A counterexample

1288-645: The Basin and Range Province of Western North America. These areas often occur when the regional stress is extensional and the crust is thinned. During and following uplift, mountains are subjected to the agents of erosion (water, wind, ice, and gravity) which gradually wear the uplifted area down. Erosion causes the surface of mountains to be younger than the rocks that form the mountains themselves. Glacial processes produce characteristic landforms, such as pyramidal peaks , knife-edge arêtes , and bowl-shaped cirques that can contain lakes. Plateau mountains, such as

1344-463: The Catskills , are formed from the erosion of an uplifted plateau. Climate in the mountains becomes colder at high elevations , due to an interaction between radiation and convection. Sunlight in the visible spectrum hits the ground and heats it. The ground then heats the air at the surface. If radiation were the only way to transfer heat from the ground to space, the greenhouse effect of gases in

1400-451: The Launceston and North-west and west local government regions of Tasmania. The locality is about 109 kilometres (68 mi) west of the town of Westbury . The 2016 census has a population of 66 for the state suburb of Cradle Mountain. Cradle Mountain was gazetted as a locality in 1966. Cradle Mountain (the mountain) occupies a small area in the north-west of the locality, which occupies

1456-461: The ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction, such as mining and logging , along with recreation, such as mountain climbing and skiing . The highest mountain on Earth is Mount Everest in the Himalayas of Asia , whose summit

1512-613: The 952 metres (3,123 ft) Mount Brandon by Irish Catholics . The Himalayan peak of Nanda Devi is associated with the Hindu goddesses Nanda and Sunanda; it has been off-limits to climbers since 1983. Mount Ararat is a sacred mountain, as it is believed to be the landing place of Noah's Ark . In Europe and especially in the Alps , summit crosses are often erected on the tops of prominent mountains. Heights of mountains are typically measured above sea level . Using this metric, Mount Everest

1568-550: The Overland Track starting from Cradle Mountain and heading south to Lake St Clair . By 1935 it was consolidated and used by independent walking parties. Cradle Mountain is formed by an igneous dolerite sill that intruded the Permian-Jurassic sedimentary layers, cooling to form a broad hard layer. Subsequent erosion from Pleistocene glaciation left caps of dolerite at Cradle Mountain, and surrounding peaks. The area around

1624-452: The US. Fold mountains occur when two plates collide: shortening occurs along thrust faults and the crust is overthickened. Since the less dense continental crust "floats" on the denser mantle rocks beneath, the weight of any crustal material forced upward to form hills, plateaus or mountains must be balanced by the buoyancy force of a much greater volume forced downward into the mantle. Thus

1680-456: The area was logged until the 1910s. Smith's son continued logging the area on private (but National Park adjacent) land from 1943 to the 1972, ending after significant public protest. Cattle and sheep grazed in Cradle Valley from 1910 to 1930. In the 1910s Gustav and Kate Cowle climbed Cradle Mountain. They found the land beautiful and Gustav proclaimed "This must be a national park for

1736-553: The atmosphere complicates the process of convection. Water vapor contains latent heat of vaporization . As air rises and cools, it eventually becomes saturated and cannot hold its quantity of water vapor. The water vapor condenses to form clouds and releases heat, which changes the lapse rate from the dry adiabatic lapse rate to the moist adiabatic lapse rate (5.5 °C per kilometre or 3 °F (1.7 °C) per 1000 feet) The actual lapse rate can vary by altitude and by location. Therefore, moving up 100 m (330 ft) on

1792-429: The atmosphere would keep the ground at roughly 333 K (60 °C; 140 °F), and the temperature would decay exponentially with height. However, when air is hot, it tends to expand, which lowers its density. Thus, hot air tends to rise and transfer heat upward. This is the process of convection . Convection comes to equilibrium when a parcel of air at a given altitude has the same density as its surroundings. Air

1848-533: The centre of the Earth, because the figure of the Earth is not spherical. Sea level closer to the equator is several miles farther from the centre of the Earth. The summit of Chimborazo , Ecuador's tallest mountain, is usually considered to be the farthest point from the Earth's centre, although the southern summit of Peru's tallest mountain, Huascarán , is another contender. Both have elevations above sea level more than 2 kilometres (6,600 ft) less than that of Everest. Dove Lake (Tasmania) Dove Lake

1904-459: The climate on the ecology at an elevation can be largely captured through a combination of amount of precipitation, and the biotemperature , as described by Leslie Holdridge in 1947. Biotemperature is the mean temperature; all temperatures below 0 °C (32 °F) are considered to be 0 °C. When the temperature is below 0 °C, plants are dormant, so the exact temperature is unimportant. The peaks of mountains with permanent snow can have

1960-534: The conditions above and below a particular zone will be inhospitable and thus constrain their movements or dispersal . These isolated ecological systems are known as sky islands . Altitudinal zones tend to follow a typical pattern. At the highest elevations, trees cannot grow, and whatever life may be present will be of the alpine type, resembling tundra . Just below the tree line , one may find subalpine forests of needleleaf trees, which can withstand cold, dry conditions. Below that, montane forests grow. In

2016-469: The continental crust is normally much thicker under mountains, compared to lower lying areas. Rock can fold either symmetrically or asymmetrically. The upfolds are anticlines and the downfolds are synclines : in asymmetric folding there may also be recumbent and overturned folds. The Balkan Mountains and the Jura Mountains are examples of fold mountains. Block mountains are caused by faults in

2072-503: The crust: a plane where rocks have moved past each other. When rocks on one side of a fault rise relative to the other, it can form a mountain. The uplifted blocks are block mountains or horsts . The intervening dropped blocks are termed graben : these can be small or form extensive rift valley systems. This kind of landscape can be seen in East Africa , the Vosges and Rhine valley, and

2128-535: The definition since the 1970s. Any similar landform lower than this height was considered a hill. However, today, the United States Geological Survey concludes that these terms do not have technical definitions in the US. The UN Environmental Programme 's definition of "mountainous environment" includes any of the following: Using these definitions, mountains cover 33% of Eurasia, 19% of South America, 24% of North America, and 14% of Africa. As

2184-460: The dry season and in semiarid areas such as in central Asia. Alpine ecosystems can be particularly climatically sensitive. Many mid-latitude mountains act as cold climate refugia, with the ecosystems occupying small environmental niches. As well as the direct influence that the change in climate can have on an ecosystem, there is also the indirect one on the soils from changes in stability and soil development. The colder climate on mountains affects

2240-523: The economies of mountain communities, with developments focused around attractions such as national parks and ski resorts . Approximately 80% of mountain people live below the poverty line. Most of the world's rivers are fed from mountain sources, with snow acting as a storage mechanism for downstream users. More than half of humanity depends on mountains for water. In geopolitics , mountains are often seen as natural boundaries between polities. Mountaineering , mountain climbing, or alpinism

2296-428: The effect disappears. Precipitation in highland areas is not increasing as quickly as in lowland areas. Climate modeling give mixed signals about whether a particular highland area will have increased or decreased precipitation. Climate change has started to affect the physical and ecological systems of mountains. In recent decades mountain ice caps and glaciers have experienced accelerating ice loss. The melting of

2352-433: The feature makes it either a hill or, if higher and steeper, a mountain. Major mountains tend to occur in long linear arcs, indicating tectonic plate boundaries and activity. Volcanoes are formed when a plate is pushed below another plate , or at a mid-ocean ridge or hotspot . At a depth of around 100 km (60 mi), melting occurs in rock above the slab (due to the addition of water), and forms magma that reaches

2408-507: The first Europeans to explore and summit Cradle Mountain were Joseph Fossey and Henry Hellyer , who were surveying for the Van Diemen's Land Company . Trappers worked in the area from the 1860s until the collapse of the fur trade in the 1950s, although hunting in the park was declared illegal after 1927. They established huts, including Du Cane and Pine Valley, and burned the land to encourage fresh growth and game. A large expanse of King Billy pines were found by James Smith in 1863, and

2464-498: The glaciers, permafrost and snow has caused underlying surfaces to become increasingly unstable. Landslip hazards have increased in both number and magnitude due to climate change. Patterns of river discharge will also be significantly affected by climate change, which in turn will have significant impacts on communities that rely on water fed from alpine sources. Nearly half of mountain areas provide essential or supportive water resources for mainly urban populations, in particular during

2520-563: The mountain has a large number of day walks, as well as being one terminus of the Overland Track . The Overland Track winds through a variety of landscapes to its opposite end—80.8 kilometres (50.2 mi) to the south—at Lake St Clair , Australia's deepest lake. The mountain is climbed by walkers virtually year round. It is a strenuous return hike from the Dove Lake car park with a recommended allotted time of six-and-a-half hours. The climb up

2576-533: The mountains cliffs. Tiger snakes are a highly venomous snake species known to be found in the area. Fungi are also a part of the park's biodiversity. While the Management Plan from 1999 for Cradle Mountain-Lake St Clair National Park only mentions fungi in the context of their destructive effects ( Phytophthora cinnamomi and Chalara australis ), the park has a variety of fungi that perform beneficial ecological roles. Parasitic fungi—often regarded negatively—are

2632-617: The northern half of Cradle Mountain-Lake St Clair National Park. Route C132 (Cradle Mountain Road / Dove Lake Road) enters from the north and runs south to Dove Lake , where it ends. Cradle Mountain sits between the Big River and Northern Tasmanian Aboriginal people . Aboriginal Tasmanians were persecuted by the European settlers upon their arrival, and the last free Aboriginals in the area were seen just south of Cradle Mountain in 1836. In 1827 and 1828,

2688-536: The people for all time. It is magnificent, and people must know about it and enjoy it". They began campaigning for the area from Cradle Mountain to Lake St Clair to be a national park, and set up a popular chalet the next year. It was declared a scenic reserve in 1922, a wildlife reserve in 1927 and its current designation of national park from 1947. During this transition former trappers began building huts and guiding bushwalkers, including Paddy Hartnett, Weindorfer and Bob Quaile. In 1931 fur trapper Bert Nichols blazed

2744-527: The plants and animals residing on mountains. A particular set of plants and animals tend to be adapted to a relatively narrow range of climate. Thus, ecosystems tend to lie along elevation bands of roughly constant climate. This is called altitudinal zonation . In regions with dry climates, the tendency of mountains to have higher precipitation as well as lower temperatures also provides for varying conditions, which enhances zonation. Some plants and animals found in altitudinal zones tend to become isolated since

2800-403: The rocky part of the mountain involves scrambling over large boulders for several hundred metres. The entire climb is exposed to any bad weather that may arrive quickly, while climbing the upper slopes in winter can be dangerous due to slick ice on the rocks and heavy snow covering holes and other hazards. From the summit, there are views of Dove Lake , Barn Bluff and Mount Ossa . The area has

2856-504: The surface. When the magma reaches the surface, it often builds a volcanic mountain, such as a shield volcano or a stratovolcano . Examples of volcanoes include Mount Fuji in Japan and Mount Pinatubo in the Philippines. The magma does not have to reach the surface in order to create a mountain: magma that solidifies below ground can still form dome mountains , such as Navajo Mountain in

2912-583: The surrounding land. A few mountains are isolated summits , but most occur in mountain ranges . Mountains are formed through tectonic forces , erosion , or volcanism , which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering , through slumping and other forms of mass wasting , as well as through erosion by rivers and glaciers . High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect

2968-470: The tallest mountain on land by this measure. The bases of mountain islands are below sea level, and given this consideration Mauna Kea (4,207 m (13,802 ft) above sea level) is the world's tallest mountain and volcano, rising about 10,203 m (33,474 ft) from the Pacific Ocean floor. The highest mountains are not generally the most voluminous. Mauna Loa (4,169 m or 13,678 ft)

3024-473: The temperate portions of the earth, those forests tend to be needleleaf trees, while in the tropics, they can be broadleaf trees growing in a rainforest . The highest known permanently tolerable altitude is at 5,950 metres (19,520 ft). At very high altitudes, the decreasing atmospheric pressure means that less oxygen is available for breathing, and there is less protection against solar radiation ( UV ). Above 8,000 metres (26,000 ft) elevation, there

3080-495: The valleys surrounding the mountain, species such as myrtle beech , pandani , sassafras , King Billy pine and celery top pine form thick temperate rainforest with dense, mossy undergrowth. Wombats are a common sight throughout the area, while pademelons , Tasmanian devils and echidnas can also be seen. Bird species in the area include green rosellas , black currawongs , pink robins and Tasmanian scrubwrens , while peregrine falcons and wedge-tailed eagles nest on

3136-529: The world) form mutually beneficial mycorrhizal relationships with fungi. Given the diversity of plants, specialist habitats and micro-climates in the park, a diversity of fungi, including lichens, is also expected to occur. Several hundred species have already been recorded by field naturalists and interested individuals and can be found in the Atlas of Living Australia . Despite their essential roles in underpinning terrestrial ecosystems, fungi are barely recognised as
