Borgarvirki
Borgarvirki lies between Vesturhóp and Víðidalur in the north of Iceland, and at 177m above sea level it dominates the surrounding region. Made out of basalt strata, it has been used as a fortress. Borgarvirki is a natural phenomenon, altered by humans in earlier centuries. In 1949, Borgarvirki was renovated by workers who installed a granite lintel at the main entrance. Borgarvirki is a volcanic plug (gosstapi ), and the Icelandic sagas mention that in earlier centuries it was used for military purposes. There is a viewing dial inside.

Volcanic Plug
A volcanic plug, also called a volcanic neck or lava neck, is a volcanic object created when magma hardens within a vent on an active volcano. When present, a plug can cause an extreme build-up of high gas pressure if rising volatile-charged magma is trapped beneath it, and this can sometimes lead to an explosive eruption. In a plinian eruption the plug is destroyed and ash is ejected. Glacial erosion can lead to exposure of the plug on one side, while a long slope of material remains on the opposite side. Such landforms are called crag and tail. If a plug is preserved, erosion may remove the surrounding rock while the erosion-resistant plug remains, producing a distinctive upstanding landform. Examples of volcanic plugs Africa Near the village of Rhumsiki in the Far North Province of Cameroon, Kapsiki Peak is an example of a volcanic plug and is one of the most photographed parts of the Mandara Mountains. Spectacular volcanic plugs are present in the center of La Gomer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vatnsnes
Vatnsnes () is a peninsula jutting into Húnaflói in northern Iceland. It is surrounded by waters of Miðfjörður on the west and Húnafjörður on the east. It is home to one of the largest seal colonies in Iceland, among others at Hindisvík and Ósar . Seals have been protected for many years in Hindisvík. A stone hut was built at Ósar on the eastern side of the peninsula for seal watching. Among geological features of Vatnsnes are Borgarvirki, a volcanic plug mentioned for its use as a fortress in the Sagas of Icelanders, and Hvítserkur (, regionally also ) is a 15 m high basalt Stack (geology), stack along the eastern shore of the Vatnsnes peninsula, in Northwestern Region (Iceland), northwest Iceland. The rock has two holes at the base, which give it the appearance of a ..., a 15 m high basalt rock formation near the eastern shore of the peninsula.

List Of Columnar Basalts In Iceland
Columnar jointed volcanic rocks exist in many places on Earth. Perhaps the most famous basalt lava flow in the world is the Giant's Causeway in Northern Ireland, in which the vertical joints form polygonal columns and give the impression of having been artificially constructed. Notable columnar jointed volcanics Africa Ikom Columnar Basalt in Cross River State, Nigeria * Bugarama in Rusizi, Rwanda Columnar jointing in Rusizi district, Nzahaha Sector. This may have formed from contractional cooling of basaltic lavas. * "Organ Pipes" near Twyfelfontein, Namibia * Numan, Nigeria * Seliana, Tunisia * Rochester Falls, Mauritius * Foreke Quarry, Foreke Dachang, Cameroon South Asia ; India In India, columnars are found in several places across the volcanic traps such as 6.5 crore or 65 million years ago (Mya) old deccan traps in South India and 14.5 crore or 145 mya old Rajmahal Traps in Eastern India. * Karnataka ** St. Mary's Island columnars near Malpe in Udupi district o ...

Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Icelandic Sagas
The sagas of Icelanders ( is, Íslendingasögur, ), also known as family sagas, are one genre of Icelandic sagas. They are prose narratives mostly based on historical events that mostly took place in Iceland in the ninth, tenth, and early eleventh centuries, during the so-called Saga Age. They were written in Old Icelandic, a western dialect of Old Norse. They are the best-known specimens of Icelandic literature. They are focused on history, especially genealogical and family history. They reflect the struggle and conflict that arose within the societies of the early generations of Icelandic settlers. The Icelandic sagas are valuable and unique historical sources about medieval Scandinavian societies and kingdoms, in particular in regards to pre-Christian religion and culture. Eventually many of these Icelandic sagas were recorded, mostly in the 13th and 14th centuries. The 'authors', or rather recorders of these sagas are largely unknown. One saga, ''Egil's Saga'', is beli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Iceland
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Iceland
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
