The locality of Nämforsen consists of three islands, Notön, Laxön and Brådön. The majority of the carvings are found on Brådön and Notön, and together there are more than 1700 figures. Notön has the largest number of engravings, c. 800 figures and Brådön c. 400. The dominant motif is the elk, of which half the number are depicted totally carved out. The other half are contour-carved. Some of the elks are only partly carved out. Most of the ship figures are single-lined with crew-strokes. Other ships are double-lined with vertical lines in the hull. The elk figures with contour-carved bodies sometimes have so called life-lines inside the body, probably showing the heart and lungs of the animal.

Because of the level above the sea at Nämforsen (72-80 mas) the oldest possible dating of the rock carvings will be 4000-3500 BC. Comparisons with motifs from other sites (Alta in Norway; Zalavruga in NW Russia) and also similar levels above the sea supports this. There are dwelling-places all around the site, which have been in use during the summer for a very long period of time, from c. 3000-1000 BC. The majority of the rock carvings seems to have been produced around 2000 BC, and they all belong to the hunter-gatherer tradition.
