Brimnes was an estate in the Upsastrond area. Nowadays its property and others belong to the municipality of Town Dalvik. According to the Svarfdaela Saga, Karl the Red and several other men were killed at River Brimnesa. He was buried in his boat.
Just north of the river one of the most interesting burial grounds of the country were inspected in 1910 by Knut Bruun and Finnur Jonsson. They discovered 13 graves, thereof one boat mound. Since then more graves and relics have been unearthened, such as another boat mound about 300 m outside the burial ground. Old sources suggest, that the boat landing Hyltinganaust was at the mouth of the river.
