The deep agricultural soils in Fitjar are found especially in the area between Lake Storavatnet and Breivika. The many stonewalls in the area reflect that the earth probably was full of stones and stone blocks. The stones that couldn't be dug out had also a function: they stored heat that helped to grow potatoes.
The permanently-protected Mosneselva River, with its meltwater from Folgefonna, runs out into Åkra Fjord by the roadless and uninhabited Mosnes. Those who once lived here were forced to surrender to the ravages of Nature. In the autumn of 1962 there was a flood so great that the people were driven from their farms.
