22-473: The Strathbogie Ranges are a set of low mountain ranges within the Great Dividing Range , rising to 1,033 metres (3,389 ft) at Mount Strathbogie. The Strathbogie Ranges are located approximately 150 kilometres (93 mi) north-east of Melbourne , Victoria . The range is the remains of a granite uplifted plateau in the southern part of the ranges and volcanic eruption in the north which formed

44-458: A 20–30-kilometre (12–19 mi) wide cauldron volcano. The topography consists of a series of ridges and undulating plateaus dissected by streams. The Strathbogie Ranges are north of the main Great Dividing Range , separated by the Goulburn River and Broken River (Victoria) valleys. This separation has produced unique biogeographic and ecological patterns. Some of the more prominent peaks of

66-625: A large national park within the range, must be reached by boat or plane. The core Aleutian Range can be divided into three mountain groups. Listed from southwest to northeast, they are: See Aleutian Islands for the continuation of the range to the west of Unimak Island. Just to the north of the Aleutian Range are the Tordrillo Mountains , the southeasternmost extent of the Alaska Range . Selected mountains: Two volcanoes erupted during

88-433: A new vineyard at Mt Helen. There are over 25 vineyards located in the region, at altitudes ranging from 150–650 metres (490–2,130 ft), with plantings on acidic sandy loams formed from decomposed granite. The main wine varieties are Chardonnay, Sauvignon Blanc, Pinot Noir and Shiraz. Mountain range Mountain ranges are usually segmented by highlands or mountain passes and valleys . Individual mountains within

110-520: A second factory was built in 1892 at Strathbogie North. A Post Office opened in Strathbogie on 10 July 1878. There are several districts located within the Strathbogie Ranges including Strathbogie and Ruffy , but no towns and few major roads; Strathbogie township has a general store and Ruffy township has 'The Pantry'. Due to the climate of the region, the type of vegetation and the topography,

132-519: Is a major mountain range located in southwest Alaska . It extends from Chakachamna Lake (80 miles/130 km southwest of Anchorage) to Unimak Island , which is at the tip of the Alaska Peninsula . It includes all of the mountains of the Peninsula. The Aleutian Range is special because of its large number of active volcanoes , which are also part of the larger Aleutian Arc . The mainland part of

154-525: 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

176-823: 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

198-538: 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

220-772: 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

242-559: 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 . Aleutian Range The Aleutian Range

264-435: The Strathbogie Ranges likely experienced periodic bushfires prior to European settlement. Several bushfires of restricted extent have burnt parts of the ranges in recent years Strathbogie 1990 and Longwood East-Creighton's Creek 2014 The major Victorian bushfires of 1851, 1939, 1983, 2003, 2006 and 2009 did not reach the Strathbogie Ranges. The Strathbogie wine region developed from the mid 1970s with Dr Peter Tisdall planting

286-575: The Strathbogie Tableland, all of which was once forested. The discovery of these artifacts is evidence of regular, though perhaps seasonal, utilization of the region by indigenous people. Squatters running sheep and hundreds of cattle took up large tracts of land in the Ranges from about 1842. The stations included Bailey Hill, Strathbogie, Springs A and Wombat Hill, predominantly in the hill country, while parts of Saintfield and Borodomanin were also in

308-623: 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

330-503: The atmosphere. These emissions formed a sulfate aerosol layer that totaled a transfer of 1.6 Tg of SO 2 into the stratosphere and disturbed flights over this area for a short period following the eruptions. The 7.9 Mw Aleutian Islands earthquake occurred in June 2014 at an intermediate depth of 107 km. The quake was caused by oblique normal faulting along the Aleutian Trench ,

352-485: 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,

374-498: The range include Mount Strathbogie (1,033 metres (3,389 ft)), Mount Wombat (791 metres (2,595 ft)), Sugarloaf (691 metres (2,267 ft)) and Mount Barranhet (832 metres (2,730 ft)). The Strathbogie Ranges are located in Taungurung country. Although the documented white history of the area generally asserts that the mountain range was not often frequented by indigenous people, stone artifacts are widely distributed across

396-405: The range is about 600 miles (1000 km) long. The Aleutian Islands are (geologically) a partially submerged western extension of the range that stretches for another 1,600 km (1000 mi). However the official designation "Aleutian Range" includes only the mainland peaks and the peaks on Unimak Island. The range is almost entirely roadless wilderness . Katmai National Park and Preserve ,

418-412: The ranges. John Gall of Wombat Hill was one of the few early settlers to remain in the district. John Kissock of Strathbogie Station arrived in the 1847, while William Forlonge later owned Strathbogie totalling 75,000 hectares (185,000 acres), and many of the other pastoral stations, between the early 1850s and 1867. In 1891 a butter factory was built at Strathbogie South (as Strathbogie was then known and

440-617: 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

462-521: 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

484-473: The summer of 2008 on the eastern Aleutian Islands. On July 12, 2008, Mount Okmok erupted, and it continued to erupt for a month. A giant, rapidly moving ash and gas cloud shot up to a height of 15,240 m as a result of this eruption. Mount Kasatochi was home to the other eruption, which occurred on August 7 and 8. This eruption also sent up a gas cloud about 15,000 high. Together, these two power volcanic eruptions deposited emissions of trace gases an aerosols into
