Langjökull Abyss
Langjökull (, Icelandic for "long glacier") is the second largest ice cap in Iceland (953 km2), after Vatnajökull. It is situated in the west of the Icelandic interior or Highlands of Iceland and can be seen clearly from Haukadalur. Its volume is 195 km³ 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 HvÃtárvatn on the Kjölur mountain road to the east and the ÞrÃstapajökull glacier to the west, near another smaller glacier, EirÃksjökull, which is not quite connected to Langjökull. It is the nearest large glacier to ReykjavÃk. The area of the glacier includes some mountains, e.g. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Tyva Republic in eas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Húsafell
Húsafell () is a sprawling farm and church estate and the former site of a rectory. It is the innermost farm in Borgarfjörður in the west county of Iceland, not far from Reykholt and Reykholtsdalur. Húsafell farm now serves as a hub of service for various types of tourists visiting and residing in its surrounding area. The Húsafell surrounding area thus includes a wide array of second homes, tent sites, holiday housing and short term lodgings. Among its amenities are a swimming pool and a golf course. The wider Borgarfjörður region is also renowned for its multitude of lakes where there is trout to be had and salmon to be lured in the many rivers where it is possible to go fishing. The actual estate of Húsafell farm stretches all the way to the roots of EirÃksjökull and Langjökull, covering all in all an area of appr. 100 square kilometers. The farm itself is situated in the midst of Hallmundarhraun, and the Húsafell birch wood of Húsafellsskógur. Due to its s ...

Hraunfossar
Hraunfossar (; in Borgarfjörður, western Iceland) is a series of waterfalls formed by rivulets streaming over a distance of about 900 metres out of the Hallmundarhraun, a lava field which flowed from an eruption of one of the volcanoes lying under the glacier Langjökull. The waterfalls pour into HvÃtá (Borgarfjörður), from ledges of less porous rock in the lava. The name comes from the Icelandic word for ''lava'' (''hraun'') and the word for ''waterfalls'' (''fossar''). The Hraunfossar are situated near Húsafell and Reykholt and the VÃðgelmir lava tube is close by. Literally a stone's throw upstream from Hraunfossar, there is another waterfall called Barnafoss. Its name, the ''waterfall of the children'', comes from an accident which is said to have taken place here in former times. There was a natural bridge over the waterfall and two children from a nearby farm fell to their deaths crossing the river on the bridge. Afterwards, the grief-struck mother had the bri ...

Shield Volcano
A shield volcano is a type of volcano named for its low profile, resembling a warrior's shield lying on the ground. It is formed by the eruption of highly fluid (low viscosity) lava, which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano. Repeated eruptions result in the steady accumulation of broad sheets of lava, building up the shield volcano's distinctive form. Shield volcanoes are found wherever fluid low-silica lava reaches the surface of a rocky planet. However, they are most characteristic of ocean island volcanism associated with hot spots or with continental rift volcanism. They include the largest volcanoes on earth, such as Tamu Massif and Mauna Loa. Giant shield volcanoes are found on other planets of the Solar System, including Olympus Mons on Mars and Sapas Mons on Venus. Etymology The term 'shield volcano' is taken from the German term ''Schildvulkan'', coined by the Austrian geologist Eduard Suess in 1888 an ...

Hveravellir
Hveravellir () is a geothermal field (high temperature field) of the Oddnýjarhnjúkur-Langjökull subglacial volcanic system in the north of Langjökull glacier. Description Hveravellir geothermal area is a small nature reserve and a tourist centre located in 600 m a.s.l. at the Kjölur mountain route between the glaciers Hofsjökull and Langjökull, Central Iceland. It is part of the Oddnýjarhnjúkur-Langjökull volcanic system. The place has been a popular resting place in highland travels since the age of settlement, 1100-1200 years ago. It is frequently mentioned in the old sagas, annals and folklore. Refuge huts have been situated there from the early beginning. The main geothermal activity is at the northern border of the large lava shield Kjalhraun . The main geothermal area covers around 2.5 km². The hot springs are of various types, geysers, fumaroles, solfataras, boiling pits and warm springs with lower temperatures. The currently active geysers only have smal ...

Deildartunguhver
Deildartunguhver () is a hot spring in Reykholtsdalur, Iceland. It is characterized by a very high flow rate for a hot spring (180 liters/second) and water emerges at 97 °C. It is the highest-flow hot spring in Europe. Some of the water is used for heating, being piped 34 kilometers to Borgarnes and 64 kilometers to Akranes. A fern called ''Struthiopteris fallax ''Struthiopteris fallax'' is a small species of fern in the family Blechnaceae. It is endemic to Iceland where it lives in close proximity to hot springs.

Borgarfjörður
Borgarfjörður () is a fjord in the west of Iceland near the town of Borgarnes. Although the waters of Borgarfjörður appear calm, the fjord has significant undercurrents and shallows. The many flat islands lying in the fjord are for the most part uninhabited. Near Borgarnes, the ''hringvegur'' (road no.1 or "ring road") passes over Borgarfjarðarbrú, a bridge of 0.5 km in length at the inland portion of the fjord. The land around the fjord has been inhabited since the time of Icelandic settlement. Events in the Icelandic sagas such as that of Egill SkallagrÃmsson are situated here. The name of the fjord seems to have come from the farm ''Borg'', which according to the sagas was founded by Egill's father SkallagrÃmur, who took the land around the fjord and accordingly gave the fjord the name of Borgarfjörður. While serving as a synonym for the various townships, farms, natural attractions and areas in the region, the various parts of Borgarfjörður are now gene ...
