Based on the detailed geomorphological analysis of the terraces of the Dnister River, and of its tributaries, and the analysis of the sections of the terrace deposits, the main stages of the history of the Dnister valley development in the north-south Forecarpathians have been presented. Some existing and already firmly establishes opinions concerning the structure of the terraces, their extent, and the time of their formation were clarified. The paleogeographical events were correlated with the stages of the oxygen isotope scale, the paleomagnetical reference points and the paleogeographical (paleoclimatical) phases. Key words: Krasna planation surface, Loyeva planation surface, Starosilska planation surface, terrace, surface of the terrace, plinth (socle) of the terrace, alluvium, glacial deposits, absolute and relative datum levels.
