Þórisjökull
Þórisjökull or Thórisjökull (, Icelandic for "Thóris's glacier") is a small glacier and volcano in western-central Iceland, to the southwest of Langjökull glacier. It has an elevation of . Kaldidalur lies in the foreground. Position þórisjökull is situated between Langjökull glacier and the shield volcano Ok to its east. The "Cold valley" (translation of Kaldidalur) is lying between them with its famous highland road of the same name. The volcano The glacier volcano Þórisjökull is a tuya from the Ice Age (in Iceland from 100,000 years ago til about 10,000 years ago). Its mountain part consists mainly of hyaloclastites. The glacier was part of Langjökull glacier probably til the end of the 18th century. Some geological research was made again on the Þórisjökull and Prestahnúkur area in 2009 and it shows clearly active volcanic fissures under the glacier which are part of the Prestahnúkur volcanic system (see weblink, Icelandic Meteorological Institute).

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] |
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. In 2009 g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaldidalur
The Kaldadalsvegur (, ) is the shortest of the highland tracks traversing the Highlands of Iceland, therefore the nickname "highlands for beginners" . Its name derives from the valley it crosses: '':is:Kaldidalur, Kaldidalur'' means "cold dale/valley". Sometimes the Kaldadalsvegur is referred to as simply "the Kaldidalur". The route begins a bit to the north of Þingvellir and to the west of the volcano Skjaldbreiður, which really comes up to its name (meaning ''broad shield''). The track continues between the glaciers Þórisjökull and Ok (glacier), Ok and leads up to the north. To the east of Reykholt, Western Iceland, Reykholt it comes near the ''Reykholtsdalur'' to Húsafell. Then it continues up to ''Hvammstangi'' at the ''Miðfjörður''. Signed as route 550 (formerly F550), the track is 40 kilometers long, and has no unbridged river crossings. (The Kaldadalsvegur is ''not'' an Roads in Iceland, F road, and a four-wheel-drive vehicle is ''not'' legally required to tr ...
