Kverkfjöll

Background

History & Background

Kverkfjöll’s history is primarily geological. The mountain group is built around an active central volcano and bears clear evidence of repeated interaction between volcanic activity and Ice Age glaciers. Parallel hyaloclastite ridges, calderas, outlet glaciers and geothermal features record periods when eruptions took place beneath or beside ice. The modern landscape remains dynamic: geothermal heat melts glacier ice, marginal water bodies form and drain, and the glacier front retreats and shifts over time. The wider Vatnajökull region is internationally important for studying these fire-and-ice processes and is part of Vatnajökull National Park’s UNESCO World Heritage property. Human use of the Kverkfjöll area remains closely tied to highland travel. Today Sigurðarskáli, operated by Ferðafélag Fljótsdalshéraðs and Ferðafélag Húsavíkur, provides the principal visitor base, while national-park rangers work in Kverkfjöll during the summer and maintain interpretation and safety information for visitors.

Kverkfjöll is one of the most extraordinary volcanic-and-glacial landscapes in the Icelandic Highlands. The mountain range rises at the northern edge of Vatnajökull and forms part of a large active central volcano. According to Vatnajökull National Park, Kverkfjöll is Iceland’s third-highest mountain group after Öræfajökull and Bárðarbunga. Two ice-filled calderas are believed to lie within the system, with caldera rims around 1,800 metres. The highest summit, Skarphéðinstindur, reaches 1,936 metres. The range is divided by Kverk, a deep pass bordered by steep rock walls. Kverkjökull flows northwest through the pass and descends toward a plateau around 900 metres above sea level. Huge outlet glaciers frame the area: Dyngjujökull to the west and Brúarjökull to the east. The Kverkfjöll ridge itself contains parallel hyaloclastite ridges formed by volcanic activity interacting with ice, making the area a natural geological classroom. Geothermal heat is a defining feature. Vatnajökull National Park describes the Kverkfjöll geothermal system as one of the most powerful in Iceland. Hot water in the river Volga helps shape ice formations at the Kverkjökull margin, while meltwater can collect in geothermal lakes and drain suddenly. Because the glacier edge changes constantly, the national park urges extreme caution around the terminus. Its official visitor trail specifically warns people not to enter the unstable ice cave: falling ice is frequent and poisonous gases can accumulate quickly. The main summer visitor base is Sigurðarskáli, at about 900 metres elevation. The hut sleeps 75 people and there is camping, cooking facilities, toilets and showers. Rangers are stationed in the area during summer. There is no shop, restaurant or fuel station, so travellers must be self-sufficient. Access is by remote mountain roads, including F902 from the F910/F903 network, and a capable 4x4 is required. Road openings vary with snow and conditions, so current road and weather information should always be checked before departure. Visitors can choose from several official trails. The short K5 interpretive trail is approximately 800 metres and takes around 45 minutes. More demanding options include the 2.1 km Virkisfell route, the 9 km Biskupsfell loop and the trail toward Kverkjökull. Kverkfjöll is not a casual roadside stop, but for well-prepared highland travellers it offers a rare combination of active volcanism, geothermal energy, moving glaciers and immense wilderness.
