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.
In one of the frame-built haysheds at Nottveit, at holding No. 3, we discover that several of the staves have a medieval look, with large dimensions and carefully rounded edges. According to tradition, it was the farms Nottveit and Mostraumen that supplied the timber for the stave church at Mo, and it is not unlikely that these farms received the old timber in return when the new church was erected there in 1593.
Tthe Otterstad farms lie in the innermost part of Mofjorden, on the northwest side of the river. The row of stave-built boatsheds that belong to the farm were probably constructed a little after the middle of the 1800s. Both here and on the Mo side, the boatsheds were important storage places at the seashore; wood and other farm products intended for the town; corn and merchandise in return.
