Þórisjökull

Þórisjökull is a glacier and mountain in western Iceland that rises to about 1,350 meters above sea level. The formation combines glacial ice with volcanic structures, reflecting the complex geological history of the region.

The glacier separated from the larger Langjökull glacier at the end of the 18th century, marking a major shift in Iceland's glacial landscape. This separation occurred as part of broader climate changes affecting glaciers across Europe during that period.

The name comes from the troll Þórir, who according to Grettis Saga inhabited a cave near the glacier in ancient times. This legend shapes how locals and visitors understand the place today.

Access is via Kaldidalur Road to a large rock cairn called Beinakerlingin at 720 meters elevation. From this point, visitors can hike further toward the glacier while being prepared for uneven terrain and changing weather conditions.

This geological formation is a type called a tuya, created by volcanic activity beneath ice sheets during the last Ice Age. Such structures are relatively rare and show Iceland's remarkable volcanic activity even under extreme conditions.
