Kerlingarfjöll’s protection value is first and foremost based on the unique and rare geology of the area. Kerlingarfjöll is categorized as an ancient central volcano that covers over 140 square kilometers and contained
therein are two caldera fragments as well as numerous acid and intermediate eruption relics. The mountains have been dated and are all presumed to have formed during the last ice age.
The oldest rock is found in Draugafell (336,000 years old) and the youngest in Fannborg (79,000 years old), but the age of the calderas is unknown. Great rhyolite mountains characterize the area and give the mountains
their unique, light color. Kerlingarfjöll is the second largest rhyolite area in Iceland, after the Torfajökull area.
