Field trip

The fieldtrip entitled «Upper Volga from the sources to the Plyos Water Gap: Fluvial system adjustment in a formerly glaciated landscape». Volga is the largest European river with the length of 3530 km and catchment area of 1,360,000 km². In it’s upper course, Volga crosses the areas covered by the last (MIS 2) and penultimate (MIS 6) glaciations that exerted much influence on the fluvial system development. The field trip is focused on the development of an ancient drainage system under the influence of successive ice sheet advances and fluvial reworking of complex glacial landscapes in the end of the Quaternary. 

Two contrasting hypotheses on the Quaternary history of the upper Volga drainage have been competing since the 1970s: drainage existence and relative stability through the whole Quaternary and its young, post-LGM age. In the last decade, a significant advance was achieved in the improvement of alluvial and lacustrine chronology, mainly due to massive OSL dating. Key sections and landforms will be shown during the field trip to reach the better understanding of the Upper Volga story, which proved to be quite unusual and much different from the concepts proposed before. The trip will take 8 days / 7 overnights (with two half-day breaks for conference sessions) and will cover total distance of 2200 km along River Volga and through its tributary catchments.
