At Grindarskörð there are series of “knuckle-knuckles”, which bear the sky from the north, and they are called Bolli. Stóri-Bolli, Mið-Bollar or Tví-Bollar and finally Þrí-Bollar . At least two of these names are used for puff pastries that have very small cup shapes, and in fact have a probability that these names have ever been given or intended for them. This is true for Stóra-Bolla and Þrí-Bolla, but another case is for Mið-Bolla or Tví-Bolla. Stóri-Bolli has poured out large lava, which extends all the way north to Undirhlíðar, but has managed to spit lava seeds on the pebbles, which has stolen its name.

Instead of Mið-Bollar I like to use the name Tví-Bollar, because both exist. The craters are namely two together and truly they can also be called Little and Big, because the little crater barely covers the others “Waist” and is on his right side looking north.

The larger crater is about 35-40 m high and about 480 m above sea level. It is open to the northwest, and the lava has flowed from there, first in steep waterfalls, and then mostly in underground channels and caves, which have branched off in various ways as they descend. The so-called Death Valley caves (Dauðadalshellar), which many recognize, are in this lava. It has flowed over the lava from Stóra-Bolla. Slender silt has flowed along Lönguhlíð and can be seen there in various ways, but the main lava has fallen into a wide waterfall all the way north to Helgafell. Finally, it sent a thin stream west through Helgafell to the southwest. It can be seen in many places that it has fallen into cracks in older lava, which the Gullkistugjá is in and is from Stóra-BoIIa.

This eruption has occurred at the time when the settlement of the Nordic people in Iceland was beginning or in the beginning. Therefore, the eruption in the Tví-Bollar at Grindarskörð may have been the first fire metabolism that our ancestors looked at in this country.
