Studies of marginal glacial features in southeastern Kola Peninsula provide evidence that the eastern part of the northern Terskiye Keyvy ridge systems began to form between the Ponoy Ice Dome and the White Sea Ice Lobe, and later developed along the margin of the latter. The process most probably occurred throughout the whole of the Early Dryas. The second marginal belt (lying farther south) was also formed by the ice lobe which flowed across the White Sea basin, but is attributed to the Middle Dryas. Therefore for the first time data are presented which clearly indicate that marginal features corresponding to the Luga and Neva glacial stages were formed in the Kola Peninsula.
