There is evidence of human settlement in Nordland as far back as 10,500 years ago, about as early as in southern Norway. These Stone Age people lived near the coast, often on islands and typically along straits near the open sea, with a rich provision of marine resources. Such archeological evidence has been found on Vega, in Leirfjord and along Saltstraumen. There are at least 15 locations with prehistoric rock carvings in Nordland, from Helgeland in the south to Narvik in the north (see Fosna-Hensbacka culture).
