Abstract. Field work in 2023 was carried out in key areas of the Kandalaksha and Tersky coasts of the White Sea. In the course of the work, new results were obtained on the morphology and geological structure of glacial formations, which were previously considered as the marginal forms of the last glaciation. Using a complex of geological, geomorphological and structural methods, it was established that the ridge and ridge-hilly relief of the Ondomozero Keiva is represented by a complex of fluvioglacial deposits, such as of kames and eskers. In some areas, these deposits are deformed and covered by a thin cover of ablation moraine. At the base of the ridges, limnoglacial and fluvioglacial sediments and basal moraines were identified. The complex of glacial deposits can be compared with marginal eskers of the northern periphery of the White Sea Ice Stream of the last glaciation. Keywords: White Sea, Kola Peninsula, Fennoscandian Ice Sheet, moraine ridges, eskers, deglaciation, last glaciation
