Geitlandsjökull
Geitlandsjökull () is a lateral glacier of Langjökull, with a flowshed of from the second largest ice cap in Iceland at , in the west of Iceland. It has also been used as the name for the substantial Langjökull ice cap, as has the name Suðurjöklar. The highest point of Geitlandsjökull, which lies on top of a tuya, reaches a height of . Unlike most of the outlet glaciers of Langjökull which are retreating, its recent mass balance is stable, as it intercepts the predominant low pressure weather systems from the south-west. In the Grettis saga ''Grettis saga Ásmundarsonar'' (modern , reconstructed ), also known as ''Grettla'', ''Grettir's Saga'' or ''The Saga of Grettir the Strong'', is one of the Icelanders' sagas. It details the life of Grettir Ásmundarson, a bellicose Icelandic ou ... the outlaw Grettir Ásmundarson climbed Geitlandsjökull and walked south from it to a grassy valley with hot springs and surrounded by glaciers on all sides.

Prestahnúkur
The peak Prestahnúkur () with a height of , is in the Western Volcanic Zone to the west of the Highlands of Iceland to the west of Langjökull glacier, or to be more specific, to the west of Geitlandsjökull glacier, a part of the Langjökull. The volcano Prestahnúkur includes the terrain under the Geitlandsjökull glacier continuous to the peak and also includes fissure fields to its north and south. The volcanic system The central volcano Prestahnúkur consists of a rhyolite tuya that was formed entirely under ice, and has been dated as 89 ± 24 , but another dating is about 60 ka. Two vents have been found. At the base of the northern flank is a geothermal area, with the rhyolite and hot springs suggesting that a long-lived magma chamber is or has been present. There has been intermittent seismic activity, mostly in an area about wide centred at the central volcano, but as no dyke intrusions have been observed, so it is unproven that the volcano is active.

Langjökull
Langjökull (, Icelandic for "long glacier") is the second largest ice cap in Iceland (), after Vatnajökull. It is situated in the west of the Icelandic interior or Highlands of Iceland and can be seen clearly from Haukadalur. It covers the higher parts of the Langjökull volcanic system. Its volume is and the ice is up to thick. The highest point of the ice cap (at ''Baldjökull'' at the northern end of Langjökull) is about above sea level. In the past, the largest recorded surface area was in 1840. Situation and form The glacier is roughly parallel to the direction of the country's active volcanic zone: north-east to south-west. It is about long and wide, and has a slightly narrower point roughly between the lake Hvítárvatn on the Kjölur mountain road to the east and the Þrístapajökull glacier to the west, near another smaller glacier, Eiríksjökull, which is not quite connected to Langjökull. It is the nearest large glacier to Reykjavík. The area o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glaciers Of Iceland
The glaciers and ice caps of Iceland covered 11% of the land area of the country, up to about 2008. this was down to 10%. They have a considerable impact on its landscape and meteorology. Glaciers are also contributing to the Icelandic economy, with a tourist market that includes glacier trips on snowmobiles and glacier hiking tours. However, the recent loss of ice due to climate change is an increasing concern in Icelandic society. Description Glaciers can both grow in size and regress depending upon several factors of which climate and precipitation in the glaciers catchment are the most important. About 7,000 years ago, the Pleistocene ice from the last Ice Age over Iceland disappeared almost entirely, so the current glaciers in Iceland are not that old. In the case of Iceland as several large glaciers are over active volcanoes, geothermal melting can be a substantial component of the glacier ice mass balance. Accordingly Iceland's glacier area varies from year to year and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iceland
Iceland is a Nordic countries, Nordic island country between the Atlantic Ocean, North Atlantic and Arctic Oceans, on the Mid-Atlantic Ridge between North America and Europe. It is culturally and politically linked with Europe and is the region's westernmost and most list of countries and dependencies by population density, sparsely populated country. Its Capital city, capital and largest city is Reykjavík, which is home to about 36% of the country's roughly 380,000 residents (excluding nearby towns/suburbs, which are separate municipalities). The official language of the country is Icelandic language, Icelandic. Iceland is on a rift between Plate tectonics, tectonic plates, and its geologic activity includes geysers and frequent Types of volcanic eruptions, volcanic eruptions. The interior consists of a volcanic plateau with sand and lava fields, mountains and glaciers, and many Glacial stream, glacial rivers flow to the sea through the Upland and lowland, lowlands.

Tuya
A tuya is a flat-topped, steep-sided volcano formed when lava erupts through a thick glacier or ice sheet. They are rare worldwide, being confined to regions which were covered by glaciers and had active volcanism during the same period. As lava that erupts under a glacier cools very quickly and cannot travel far, it piles up into a steep-sided hill. If the eruption continues long enough, it either melts all the ice or emerges through the top of the ice and then creates normal-looking lava flows that make a flat cap on top of the hill. Discovering and dating the lava flows in a tuya has proven useful in reconstructing past glacial ice extents and thicknesses. Formation Tuyas are a type of subglacial volcano that consists of nearly horizontal beds of lava capping outward-dipping beds of fragmental volcanic rocks, and they often rise in isolation above a surrounding plateau. Tuyas are found in Iceland, British Columbia, the Santiam Pass region in Oregon, the Tuva, Tyva Republic i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Cap
In glaciology, an ice cap is a mass of ice that covers less than of land area (usually covering a highland area). Larger ice masses covering more than are termed ice sheets. Description By definition, ice caps are not constrained by topographical features (i.e., they must lie over the top of mountains). By contrast, ice masses of similar size that ''are'' constrained by topographical features are known as ice fields. The ''dome'' of an ice cap is usually centred on the highest point of a massif. Ice flows away from this high point (the ice divide) towards the ice cap's periphery. Ice caps significantly affect the geomorphology of the area they occupy. Plastic moulding, gouging and other glacial erosional features become present upon the glacier's retreat. Many lakes, such as the Great Lakes in North America, as well as numerous valleys have been formed by glacial action over hundreds of thousands of years. The Antarctic and Greenland contain 99% of the ice volume on earth, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grettis Saga
''Grettis saga Ásmundarsonar'' (modern , reconstructed ), also known as ''Grettla'', ''Grettir's Saga'' or ''The Saga of Grettir the Strong'', is one of the Icelanders' sagas. It details the life of Grettir Ásmundarson, a bellicose Icelandic outlaw, and is set in the eleventh century. Overview ''Grettis saga'' is considered one of the Sagas of Icelanders (''Íslendingasögur''), which were written down in the thirteenth and fourteenth centuries and record stories of events that supposedly took place between the ninth and the eleventh centuries in Iceland. The earliest manuscript of ''Grettis saga'' was written down some time just before 1400 CE, and the saga is thought to have been composed in its current form in the fourteenth century, making it a relatively late addition to the genre.. Introduction. ''The Saga of Grettir the Strong'', p. ix The author is unknown but it is believed that the saga may have been based on a previous account of Grettir's life written by ...
