Nedre Helland- skred
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.
Manger
Mangerite is a rock type that was first made famous in a treatise by the Bergen geologist Carl Fredrik Kolderup in 1903. The rock type got its name from the place where it was found, and has made the Mangerud name well known around the world, at least among geologists.
