The main source of the Axe River is in the shallow
valley between Mt Burfell and Pass
Leggjarbrjotur. It meanders thought the Axe River Valley, across the
Bishops’ Lava Field, where it has deposited sand and gravel during the
millennia and changed its course a few times. According to Sturlunga Saga it was diverted to run over the
brink of the Almannagja fault to bring fresh water supplies closer to
the assembly area of the ancient parliament.
The present concrete
bridge by the Drowning Pool was built in connection with the
festivities and celebrations of the millennium of the parliament in
1930. The river has an average flow of 3-4 m³/sec., but sometimes
swells during spring and early summer, when the winter snow melts.
Geese breed on the small islands and harlequin ducks are frequently
seen on the water.
