river Laxá flows swiftly in a narrow channel
in the 2300 years old Laxá-lava.
The channel has steep sides, overgrown with grass and lichens,
and birch wood in places. Blackfly larvae and pupae on the river bottom
sustain a rich bird life and an abundance of Brown Trout.
The river banks are overgrown with grass, which is typical of the
spring-fed rivers in Iceland which have a very stable water level.
