Road cuts in various fine-grained semipelitic and calc-silicate schists of the Middle Nappe of the Helgeland Nappe Complex, cut by fine- to medium grained leucogranitic dikes. Both the schists and the dikes are strongly folded, caused by crustal deformation during the Caledonian Orogeny. Dating of similar dikes further to the north yielded an age of 431 million years. Being a key locality for the rocks of the Middle Nappe, the site is also visually impressive.

Today this site is only in use for scientific purposes. These road cuts expose a beautiful pattern that draws the attention to anyone passing by. However, the high speeds at the road and the limited possibilities for parking at the moment makes this site somewhat difficult to access for a general public.
