Glacial striations and ice-marginal forms such as lateral moraines and meltwater channels show that a major north-westerly-directed ice flow invaded the Oppdal area prior to the Younger Dryas (YD) Chronozone. Through the main valley from Oppdal to Fagerhaug and Berkåk, a northerly ice flow followed the major northwesterly-directed flow and is correlated with the early YD marginal deposits in the Storås area. A marked, younger, westerly-directed iceflow from a late-glacial dome east of the Oppdal area is thought to correspon with the Hoklingen ice-marginal deposits dated to the late YD Chronozone in the Trondheimsfjord district. In the main Oppdal-Fagerhaug-Berkåk valley, this younger ice flow turned to the southwest and can be traced southwards to the Oppdal area where it joined the remnants of a glacier in the Drivdalen valley.
