Lómagnúpur
Lómagnúpur (; ) is a subglacial mound in southern Iceland. Location The mountain lies in the far east of Fljótshverfi district and borders directly on Skeiðarársandur. East of it on the Sander is the Núpsvötn river. South of it is Route 1. With the bridge construction in the east of the mountain, the ring road was closed in 1974. Geology It is a long, north–south oriented ridge at its highest peak 764m above sea level, while the foremost cliffs reach a (almost vertical) height of 671m and are thus the highest in Iceland. Most of Lómagnúpur is made of palagonite, but there are also layers of lava (e.g. pillow lava and lava columns) and sediments. It was built up within a million years. The lowest layers are about 2.5 million years old, the highest ones about 1.5 million. In addition, the mountain was in interglacial times and directly on the coast immediately after the last ice age 10,000 years ago, so that the sea also left its mark on it.

Núpsvötn
Núpsvötn is a glacial river on Skeiðarársandur in Iceland. It is created by the confluence of the rivers Núpsár and Súla west of the Skeiðarárjökull. South of Lómagnúpur, Núpsvatn merges with Hverfisfljót, which flows to the sea. Núpsvötn bridge The bridge over Núpsvötn is a 430-meter one lane bridge built in 1973. In December 2018, it was the site of a car accident were three British tourists died and four were seriously injured after their car went off the bridge and fell eight meters to the Bank (geography), riverbank below. The accident highlighted the state of the road system in Iceland, especially in the southern region, and the increased pressure on it due to the increase of tourists in the country. In 2022, the accident was covered in the investigative TV-show ''Kveikur'' on RÚV. References {{DEFAULTSORT:Nupsvotn Rivers of Iceland ...

Route 1 (Iceland)
Route 1 or the Ring Road ( or ) is a National road (Iceland), national road in Iceland that circles the entire country. As a major Trunk road, trunk route, it is considered to be the most important piece of transport infrastructure in Iceland as it connects the majority of towns together in the most densely populated areas of the country. Economically, it carries a large proportion of goods traffic as well as Tourism, tourist traffic. The total length of the road is , making it the longest ring road in Europe. The road was completed in 1974, coinciding with the 1,100th anniversary of Settlement of Iceland, the country's settlement when the longest bridge in Iceland, crossing the Skeiðará river in the southeast, was opened. Previously, vehicles intending to travel between southern settlements, e.g. Vík to Höfn, had to travel north of the country through Akureyri, making the opening a major transport improvement to the country. Many popular tourist attractions in Iceland, su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skeiðarársandur
Skeiðarársandur () is an Icelandic glacial outwash plain, a vast expanse of sand generated by the transport of debris by the Skeiðará and other rivers, whose flow is generated by the Skeiðarárjökull glacier and fed by the volcanic systems of Grímsvötn and Öræfajökull. The coastline of the Sandur is 56 km long (from Hvalsík to Hnappavallaós). From Skeiðarárjökull—the valley glacier of Vatnajökull—to the sea is 20 to 30 km. The Skeiðará was the most important obstacle in the construction of Iceland's Route 1 (Iceland), Route 1. It was not until 1974 that it could be completely closed by a 904 m long bridge. This is currently the longest bridge in Iceland. It was temporarily destroyed by water masses and blocks of ice during the last major jökulhlaup, glacial outburst flood in 1996, triggered by an eruption of the Grímsvötn volcano, but was immediately restored. The outwash plain originated primarily as alluvial land, i.e. as an accumula ... [...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.

Subglacial Mound
A subglacial mound is a type of subglacial volcano formed when lava erupts beneath a thick glacier or ice sheet. The magma forming these volcanoes was not hot enough to melt a vertical pipe right through the overlying glacial ice, instead forming hyaloclastite and pillow lava deep beneath the glacial ice field. Once the glaciers had retreated, the subglacial volcano would be revealed, with a unique shape as a result of their confinement within glacial ice. They are somewhat rare worldwide, being confined to regions which were formerly covered by continental ice sheets and also had active volcanism during the same period. They are found throughout Iceland, Antarctica and the Canadian province of British Columbia. Subglacial mounds can be mistaken for cinder cones because they may have a similar shape. An example of this confusion is Pyramid Mountain in the Wells Gray-Clearwater volcanic field The Wells Gray-Clearwater volcanic field, also called the Clearwater Cone Group, is a p ...

Palagonite
Palagonite is an alteration product from the interaction of water with volcanic glass of chemical composition similar to basalt. Palagonite can also result from the interaction between water and basalt melt. The water flashes to steam on contact with the hot lava and the small fragments of lava react with the steam to form the light-colored palagonite tuff cones common in areas of basaltic eruptions in contact with water. An example is found in the pyroclastic cones of the Galapagos Islands. Charles Darwin recognized the origin of these cones during his visit to the islands. Palagonite can also be formed by a slower weathering of lava into palagonite, resulting in a thin, yellow-orange rind on the surface of the rock. The process of conversion of lava to palagonite is called ''palagonitization.'' Palagonite soil is a light yellow-orange dust, comprising a mixture of particles ranging down to sub-micrometer sizes, usually found mixed with larger fragments of lava. The color ...

Mountains Of Iceland
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 above 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 the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains te ...
