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.

August 31st 2014. A small fissure eruption has started again in Holuhraun lava North of Dyngjujökull glacier in Vatnajökull glacier.
The eruption site is outside of the glacier, the fissure is estimated 1.5 km long with lava flowing to northeast. No volcanic ash has been detected by the radar system.
Alert Phase continues to be in effect Aviation color-code set by the Icelandic MetOffice was raised over the eruption site from orange to red.
All airports, international and domestic, are open. Highland closures remain in effect
