Thórsmörk (Icelandic : Þórsmörk, [ˈθouːrsmœrk] ( Loudspeaker.svg listen )) is a mountain ridge in Iceland that was named after the Norse god Thor (Þór). It is situated in the south of Iceland between the glaciers Tindfjallajökull and Eyjafjallajökull. The name "Thórsmörk" properly refers only to the mountain ridge between the rivers Krossá, Þröngá, and Markarfljót, [1] but is sometimes used informally to describe a wider area that includes the region between Thórsmörk and Eyjafjallajökull. Thórsmörk is one of the most popular hiking areas in Iceland.


In the valley, the river Krossá winds between the mountains. The valley is closed in between glaciers, Mýrdalsjökull being at the rear end of the valley. This leads to an especially warm climate, better than in the rest of south Iceland. In the protected valley, green vegetation of moss, fern, birchwood, and other small shrubs are found.

Thórsmörk is popular amongst hikers. Many different tours are possible, from hiking on the glaciers to trekking (i.e., Laugavegur up to Landmannalaugar) or smaller excursions, such as to the canyon Stakkholtsgjá with its waterfall or five small day treks, to the summits of surrounding peaks, with rewarding views, even in bad weather. The Krossá is a cold, fast river coming down from glaciers; a bridge allows pedestrians to cross. Coaches arrive daily from Reykjavík and other towns in Iceland.

Volcanic ash from Eyjafjallajökull

During the spring 2010 eruptions of Eyjafjallajökull, much of the area was covered in a thick layer of volcanic ash. Several months were needed for nature to return to normal.

Geography of Iceland overview about the geography of Iceland

Iceland is an island country at the confluence of the North Atlantic and Arctic oceans, east of Greenland and immediately south of the Arctic Circle, atop the constructive boundary of the northern Mid-Atlantic Ridge about 860 km (530 mi) from Scotland and 4,200 km (2,600 mi) from New York City. One of the world's most sparsely populated countries, Iceland's boundaries are almost the same as the main island – the world's 18th largest in area and possessing almost all of the country's area and population. It is the westernmost European country, and has more land covered by glaciers than in all of continental Europe. The total size is 103,125 km2 (39,817 sq mi). It has an Exclusive Economic Zone of 751,345 km2 (290,096 sq mi).

Kebnekaise Swedens highest mountain

Kebnekaise is the highest mountain in Sweden. The Kebnekaise massif, which is part of the Scandinavian Mountains, has two main peaks. The glaciated southern peak used to be the highest at 2,120 metres (6,960 ft) above sea level, but has shrunk by 24 meters during the last 50 years, making the northern icefree peak at 2,096.8 metres (6,879 ft) the highest. Kebnekaise lies in Swedish Lapland, about 150 kilometres (93 mi) north of the Arctic Circle and west of Kiruna near the Kungsleden hiking trail between Abisko and Hemavan.

Volcanology of Iceland

The volcanoes of Iceland include a high concentration of active ones due to Iceland's location on the mid-Atlantic Ridge, a divergent tectonic plate boundary, and its location over a hot spot. The island has 30 active volcanic systems, of which 13 have erupted since the settlement of Iceland in AD 874.

Mýrdalsjökull glacier

Mýrdalsjökull is an ice cap in the south of Iceland. It is to the north of Vík í Mýrdal and to the east of the smaller ice cap Eyjafjallajökull. Between these two glaciers is Fimmvörðuháls pass. Its peak reaches 1,493 m (4,898 ft) in height and in the year 1980 it covered an area of approximately 595 km2 (230 sq mi).

Eyjafjallajökull glacier and volcano in Iceland

Eyjafjallajökull is one of the smaller ice caps of Iceland, north of Skógar and west of Mýrdalsjökull. The ice cap covers the caldera of a volcano with a summit elevation of 1,651 metres (5,417 ft). The volcano has erupted relatively frequently since the Last Glacial Period, most recently in 2010.

Highlands of Iceland area in Iceland

The Highlands of Iceland are a sparsely inhabited plateau that covers most of the interior of Iceland. They are situated above 400–500 metres and are mostly an uninhabitable volcanic desert, because the water precipitating as rain or snow infiltrates so quickly into the ground that it is unavailable for plant growth. This results largely in a surface of grey, black or brown earth, lava and volcanic ashes. A few oasis-like areas, such as Herðubreiðarlindir near Askja, are found only in proximity to rivers.

Landmannalaugar mountain

Landmannalaugar is a place in the Fjallabak Nature Reserve in the Highlands of Iceland. It is at the edge of Laugahraun lava field, which was formed in an eruption around the year 1477. It is known for its natural geothermal hot springs and surrounding landscape.

Skógafoss Waterfall on the Skógá River in Iceland

Skógafoss is a waterfall situated on the Skógá River in the south of Iceland at the cliffs of the former coastline. After the coastline had receded seaward, the former sea cliffs remained, parallel to the coast over hundreds of kilometres, creating together with some mountains a clear border between the coastal lowlands and the Highlands of Iceland.

Seljalandsfoss waterfall

Seljalandsfoss is a waterfall in Iceland. Seljalandsfoss is located in the South Region in Iceland right by Route 1 and the road that leads to Þórsmörk Road 249. The waterfall drops 60 m (197 ft) and is part of the Seljalands River that has its origin in the volcano glacier Eyjafjallajökull. Visitors can walk behind the falls into a small cave.

Pithoragarh district District in Uttarakhand, India

Pithoragarh is the easternmost district in the state of Uttarakhand, India. It is located in the Himalayas and has an area of 7,110 km2 (2,750 sq mi) and a population of 483,439. The city of Pithoragarh, located in Saur Valley, is its headquarters. The district is within the Kumaon division of Uttarakhand state. The Tibet plateau is situated to the north and Nepal is to the east. The Kali River originates from Kalapaani and flows south, forming the eastern border with Nepal. The Hindu pilgrimage route for Mount Kailash-Lake Manasarovar passes through this district via Lipulekh Pass in the greater Himalayas. The district is administratively divided into six tehsils: Munsyari; Dharchula; Didihat; Berinag; Gangolihat; and Pithoragarh. Naini Saini Airport is the nearest civil airport, but it does not have regular scheduled commercial passenger service. The mineral deposits present in the district are magnesium ore, copper ore, limestone and slate. There are 11 tehsil.

Lónsöræfi protected area

Lónsöræfi is a wilderness area in south-east Iceland. The region is characterised by its varied geological formations. These mostly date from a period between 5 to 7 million years ago, when the volcano Kollumúlaeldstöðvar was active. The glacier tongues of the eastern extreme of Vatnajökull also impose themselves on the area. Visible to the north-west is Snæfell (1833m), the highest peak in Iceland that isn't part of a glacier. The mountains within the area itself include Sauðhamarstindur (1319m) and Jökulgilstindar.

Tindfjallajökull mountain in Iceland

Tindfjallajökull is a stratovolcano in the south of Iceland. It has erupted rocks of basaltic to rhyolitic composition, and a 5-km-wide caldera was formed during the eruption of the 54,000-year-old Thórsmörk Ignimbrite. It is capped by a glacier of 19 km². Its highest peak is Ýmir (1462m), which takes its name from the giant Ýmir of Norse mythology. The most recent eruption was at an unknown time in the Holocene.

Hausstock mountain in the Glarus Alps

The Hausstock is a mountain in the Glarus Alps, at an elevation of 3,158 m (10,361 ft) on the border between the cantons of Glarus and Graubünden. It overlooks the valleys of Linth and Sernf rivers in Glarus, and the valley of the Vorderrhein river in Graubünden. The Hausstock was the site of the 1799 withdrawal of the Russian army under General Alexander Suvorov. A well-known destination already in the nineteenth century with British and American climbers, the mountain remains popular with mountain climbers and skiers.

Fimmvörðuháls ridge between glaciers in Iceland

Fimmvörðuháls is the area between the glaciers Eyjafjallajökull and Mýrdalsjökull in southern Iceland. The route between Skógar and Thórsmörk goes through this pass and is one of the most popular walking routes in Iceland, despite being 22 kilometres (14 mi) long and involving 1,000 metres (3,300 ft) of climbing. At Fimmvörðuháls, there is a comfortable, modern mountain hut owned by Útivist, one of the Icelandic hiking associations. Also nearby is an older, less well-equipped hut called Baldvinsskáli. The route from Skógar is particularly beautiful, as numerous waterfalls are passed along the way. The route is only accessible between mid-June and late-August. On the night of 16 May 1970, three travellers died in the mountain pass in a snowstorm.

2010 eruptions of Eyjafjallajökull volcanic events in Iceland

The 2010 eruptions of Eyjafjallajökull were volcanic events at Eyjafjallajökull in Iceland which, although relatively small for volcanic eruptions, caused enormous disruption to air travel across western and northern Europe over an initial period of six days in April 2010. Additional localised disruption continued into May 2010. The eruption was declared officially over in October 2010, when snow on the glacier did not melt. From 14–20 April, ash from the volcanic eruption covered large areas of Northern Europe. About 20 countries closed their airspace to commercial jet traffic and it affected approximately 10 million travellers.
