Litlandsvatnet
Large quantities of nickel ore have been mined from Litlandsvatnet, between Lonevågen and Hosanger. The discovery was made in 1875. During the period of operation from 1882 to 1945, 4170 tonnes of pure nickel were extracted from 462 000 tonnes of ore, a large production by Norwegian standards.
Mjøsvågen
Around Mjøsvågen here is still a compact marine use area. Some of the buildings are common boathouses, but most of them also house small enterprises and workshops. This is where the farmers from Øvsthus, Mjøs, Hole and other farms have supplemented their meagre incomes as smiths, brass moulders, clog makers, chest builders and decorative painters.
Valestrandsfossen- tanning industry
Valestrand became a centre for the tanning industry in Osterøy; one of the old crafts that has developed into a local industry with many places of work. From the 1870s ever more ventures were started. Many of the large sea houses we see today around the bay have been places for tanning and leather enterprises.
Fosnstraumen
At the southern end of the bridge between Radøy and Fosnøy archaeologists found an unusual Stone Age settlement. There was a thick “cultural layer” here with the remains of the waste dumps of a hunting people. The place was called Kotedalen. Here they came, one group after the other, and settled for some weeks, some months, or maybe years before they went on, leaving the settlement deserted. Time after time it happened. At least 16 settlement phases have been identified, stretching over 5,500 years.
Vågenes
On Vågenes, on one of the prominences out toward Eitrevågen, one finds garnets in anorthosite. The garnets are both older, and not least bigger, than average.
