Standing on the top of Volcano Trölladyngja in Ódáðahraun

At 1,468 metres (4,816 feet) tall, it is the tenth largest mountain in the country; it rises about 600 metres (1969 feet) from the surrounding Ódáðahraun lava fields and desert. Its diameter is even more impressive, as it is 10 kilometres wide. It has an oblong crater that is 1,500 metres (4921 feet) at its widest, and 100 metres (328 feet) deep.
Trölladyngja is still active, last erupting in 1961. Earthquakes around it are monitored closely. Most of its lava fields have flowed in a northerly direction, with one branch of it reaching the valley of Bárðardalur, a distance of roughly 100 km.
Shield volcanoes are formed by highly fluid lava with low viscosity pouring from a crater in all directions, travelling far before solidifying, and giving the peaks their distinctively gentle slopes.

Situated in the Ódáðahraun lava field, Trölladyngja is the biggest of the Icelandic shield volcanoes, reaching a height of 1,468 metres (4,816 ft) above sea level, and rising almost 600 metres above the surrounding desert and lava fields.
It is about 10 kilometres in diameter and its inclination is 4 to 5° in the lower slopes, but 6 to 8° at higher elevations. Its oblong crater is about 1,200 to 1,500 metres in length, 500 metres broad, and about 100 metres deep.
Most of its lava fields have flowed in a northerly direction, with one branch of it reaching the valley of Bárðardalur, a distance of roughly 100 km.

It produced a lava field of more than 85 km2 (33 sq mi) and 1.4 km3 (0.34 cu mi) – the largest in Iceland since 1783
