Spatial distribution, paragenesis and geological structure of glacial and fluvioglacial topography at the Dnieper-Kasplya interfluvial area was considered, the ice sheet dynamics and structure being thus reconstructed. The glacial landforms form bands which indicate the Valdai ice margin position during its retreat. The marginal landforms appeared to be spread in the region much wider than previously thought. The bands are discontinuous which makes difficult their tracing over long distance. Most marginal features are small ridges, with the exception of the Vitebsk upland. Marginal features structure suggests the active ice deglaciation. The ice margin had no festoons which were probably due to the flat pre-Valdaian topography.
