The Fnjóská is a headwaters in northern Iceland .

Fnjóská has a length of 117 km. Their water volume is given as 43 m³ / s. The average amount of water in summer is 20–150 m³ / s, in winter 20–30 m³ / s. The most significant tide measured in it produced 500 m³ / s. For a spring river it shows strong fluctuations in the amount of water and an equally unusually strong current.

course

The river's sources are in the highlands of Iceland , in the northern Sprengisandur area, and its waters first flow through the Bleiksmýrardalur . In Fnjóskádalur , named after the river, it then flows along the forest area Vaglaskógur , finally making a clear turn to the west, overcoming the mountain range between the valley and the Eyjafjörður in the breakthrough valley Dalsmynni and finally flowing into the Eyjafjörður in Höfðahverfi .

fishing

The Fnjóská is a popular fishing area, especially for salmon, but also for trout.

Fnjóskadalur

The Fnjóskadalur is a larger valley shaped by glaciers and the Fnjóská River over the millennia. It has a length of no less than 30 km, but is rather narrow with correspondingly little underland. The mountains to the east, aptly called Austurfjöll , near Lake Ljósavatn, are steep and quite high (around 1,000 m) with gorges and fields of firn snow. The mountains in the west show only slightly sloping slopes in the direction of the valley. The part of the valley called Dalsmynni, north of the Hringvegur , shows steep slopes, rock layers with a steep slope in the direction of the valley, above which other layers lie that are several million years younger.

geology

If you come from Eyjafjörður, you can see traces of water erosion on the other side of the valley from the Vaðlaheiði pass . The clearly demarcated edges are traces of former lakes, three of them were here in different phases of the Ice Age. When the Ice Age glaciers thawed, the glacial lakes first formed, and these eventually created the breakthrough in Dalsmynni.

As a trench-like extension of the Fnóskadalur, the Austurheiði, also created by erosion by the Ice Age glaciers, extends north to the sea over the Flateyjarskagi peninsula . However, the deserted valley of the Austurheiði is separated from the Fnjóskadalur by a (low) watershed.

Settlement

The Fnjóskadalur was never densely populated, but is now largely completely unpopulated.
