Thermoluminescence dating has been carried out on feldspar sand grains from the distal sandur of the Godøya Formation and correlated sediments at Sunnmøre, western Norway. The accumulated dose was determined by the regeneration method. The Godøya Formation, which was earlier assumed to be of Middle Weichselian age, was dated to 105–130 ka and is now assumed to postdate immediately the Eemian interglacial. Dates of sediments previously correlated to the Godøya Formation yielded ages in the ranges of 70–90 and 40–50 ka, thus indicating at least three Weichselian ice‐free periods predating the Ålesund interstadial in the area.
