The Oppstadhornet rockslide is a 10 Mm3 slide that occurs on the island of Otrøya in westernmost Norway. Terrestrial cosmogenic nuclide dating indicates that the Oppstadhornet rockslide became active ca. 16.6-14.2 kyrs ago when the retreat of the Scandinavian ice sheet exposed the island from the co...
