The Dyngjuhals is a wide ridge east of
Lakes Gaesavotn. It is about 20 km wide and continues to the north from the glacier's
edge all the way to the shield volcano Trolladyngja
(1460 metres). On
top of the volcanic ridge there are at least five crater rows side by side between 5 and 10 km long, making this
relatively small area the most volcanic in the country.
Lava flows from
those crater rows are found in the Vonarskard Pass in the southwest and along the glacial river
Skjalfandafljot towards northwest.
The 4wd track lies across it from west to east
and sometimes it disappears under slow melting snow patches, especially further east. They along with
the sometimes flooded areas east of the hill Urdarhals are the most difficult obstacles
en route. The highest point of the track across the ridge lies 1222 m
(4,032 feet) above sea level.
