Abstract. During field work in 2022–23 new data on the geological structure of the glacial relief of the Solovetskie Islands were obtained. Structural analysis of the orientation of the dip directions of foliation and bedding in basal and imbricate moraines was carried out, as well as an analysis of the dip directions of the long axes of pebbles and boulders. Analysis of the data obtained made it possible, with varying degrees of reliability, to reconstruct the directions of glacier pressure during the formation of the glacial landscape. Comparison of the obtained data with the spatial position of individual ridges and ridge-hilly massifs of the islands made it possible to construct a network of the most probable positions of the successive retreat of the ice sheet. Preliminary correlation of these positions with existing schemes of degradation of the last glaciation in the region will make it possible to compare them with the Neva (Syamozero) stage and its oscillations.
