If you journey along Austfjorden, you at the same time turn the pages of time back through Ice Age history. The landforms show how the landscape has developed gradually as the glaciers have grown - and melted again - in several episodes: from small cirques, we see innermost at Dyrdal, to larger fjords, like at Mas fjord further out.
Until 1743 the people from Modal had to wait for a flood in MOSTRAUMEN before they could draw their boats up the river current, and then row back across Lake Movatnet. But, that year the flood opened a free passageway all the way to Mo. Hordaland had gained a new tidal waterway.
Many still remember when the avalanche struck Nedre Helland, on the 14th of August, 1953 14:30 o'clock. All of the buildings at one of the farms and the main house on the neighbouring farm were destroyed. The one woman who was inside a building escaped, frightened but unharmed. The same with the others who lived at Nedre Helland; everyone was a safe distance from the avalanche.
The regulation of Lake Storavatnet has created a rare geological phenomenon: When Herlandsfossen power station taps the reservoir during the spring and summer, the old shoreline of hard bedrock comes into view.
The peat bogs on Toska have been mined for peat since 1946, when the island got electricity. In this treeless coastal landscape, peat was the most important source of energy, and this took quite a toll on the bogs.
Eksingedalen alternates between wide, flat flood plains with good farmland, and narrow passages with waterfalls where the roads cling to the mountainsides. The alternations in the landscape are a result of the sculpturing work by glaciers over several ice ages, and the deposition of the glacial river deposits when the last glacier finally melted back.
