The massif of Dovrefjell is part of the Scandes Mountains and lies near the 62nd parallel and the 9th east meridian. Snöhetta (2,286 m a.s.l.) is its highest summit (glacial belt). In these mountains, periglacial activity is determined by the observation of authentic periglacial features at 900 m a.s.l. The standard periglacial belts include three successive levels in which the morphological indicators of periglacial activity are increasingly developed with altitude. However, research carried out on the slope of Sletthøi (1,441 m), a peripheral mountain of Snöhetta, shows that it disrupts the regularity of the layout of these belts. Sletthøi displays periglacial features which do not seem to be in accordance with altitude, thus raising the problem of their morphodynamic significance. The surveys show an example of a recent periglacial recovery in a névé site from the Little Ice Age, in relation to thawing permafrost. They underline the spatial and temporal irregularities of the functional periglacial belt.
