Hofsjökull Glacier is situated in the western part of Iceland’s highlands and comes in as third largest glacier after Vatnajokull and Langjökull glaciers. Its ice cap is about 40km wide and covers a circular area of 925sq.Km.
Hofsjökull glacier is the source of Iceland’s longest river, Thjorsa which is 230km long. Other rivers that emanates from Hofsjokull include; Heradsvotn, Olfusa, and Blanda. Additionally, Hofsjökull ice cap covers an inactive sub-glacial volcano with caldera known as Hofsjökull volcano.
The central caldera of Hofsjökull volcano is estimated to be 7 by 11 km wide and is located under the western region of the Hofsjökull ice cap.
No eruptions has been witnessed from the main crater for the last 12000 years even though the northern and eastern flank fissures of the icecap have generated basaltic lava flows during Holocene period.
Kerlingarfjöll mountains are located south east of Hofsjökull glacier ice cap. Kerlingarfjöll mountain range is glacially carved covering an area of 150sq.Km and is perceived as part of the Hofsjökull volcanic system.
The volcanic inception of the mountains is also confirmed by the amazingly vivacious fumaroles’ action at Kerlingarfjöll, and additionally, by the phenomenal red-shaded earth hues which are because of the volcanic rhyolite stone from which the mountains are created.
Kjölur Highland Road which lies between the Langjökull and Hofsjökull ice sheets makes the region accessible, driving along the (Hellisheidi) heath in 4WD vehicles. Most Highland courses include crossing unbridged waterways.
As anyone might expect, the particular excellence of the scene, its once in a while observed unprecedented hues and astounding shapes, alongside the feeling of, certainly – being ‘far from everything’, make Kerlingarfjöll mountain famous with climbers.
The mountain crests rise 800–1,500 m above ocean level, over a zone sprinkled with gorges, ravines, icy scapes, mountain passes, stunning volcanic arrangements and hot geothermal spots including ethereal colours, along the many climbing trails.
