Kúðafljót, a big glacial river formed by the rivers Eldvatn, Tungufljót, Hólmsá and Skálm. About 4 km wide and difficult to ford before it was bridged, because of quicksands.
Seals and trout in the river mouth.
The Irish settler Vilbaldi had a boat named Kúði, from which the river gets its name. It is thought the boat may have been an Irish coracle.
