This is where the four counties; Árnessýsla, Borgarfjarðarsýsla, Mýrarsýsla and Húnavatnssýsla meet. Langjokull glacier (Langjökull) is known to be the second largest glacier in Iceland.
Most of its glacier rises from around 1,200m to 1,300m above sea level and covers an area of approximately 950sq.km. Although, a thorough research has not yet been conducted it’s known that Langjokull lies on a massif of hyaloclastite valleys which rise highest beneath Langjokull’s southern and northern parts.
Most of Langjokull glacier nozzles creep down towards the lower regions, and each one of them has a name. At the foot of the nunatak Fjallkirkjan, Langjokull hosts the Iceland Geological Society where they own a hut.
Just around the main glacier, there are other smaller glaciers namely: Eiriksjökull which lies to the northwest, Thorisjökull to the south, and Hrútfell towards the east.
Langjokull volcano consumes north east half of the Langjokull glacier ice cap, east of the famous pleistocene period table mountain Eirikjökull. It lies at the northern end of an active volcanic zone that stretches to the northern end of Reykjanes Peninsula.
Postglacial lava flows along Langjokull on the eastern, northern and western sides. Moreover, some shield volcanoes have been made along fissure zones.
Some of the rarest natural occurrences of Iceland like Geysir and Strokkur can be seen at Geysir geothermal area. This is the place with the largest geysers in Iceland and lies in the Haukadalur basin, near the southern end of the long fissure system stretching from Langjokull central volcano.
Additionally, one can see hot spring Blesi along with its amazing colours at Geysir geothermal area as well as other geothermal structures.
These are the two biggest highland roads that lead alongside the Langjokull glacier. Kaldidalur is located at Langjokull glacier in the west while Kjolur is located between Langjokull and Hofsjökull in the east.
Although there is very little water that runs from Langjokull glacier on the surface, Langjokull supplies Pingvallavatn by the sub-surface streams. Pingvallavatn is the largest natural lake in the country.
