Pleistocene glaciation in the east of the Russian Plain: Ural or Scandinavian glacier? | Die pleistozane Vergletscherung im Osten der Russischen Ebene: Zentrum im Ural oder Skandinavien?
A widespread occurrence of boulders and pebbles of Ural origin, forming watershed deposits and denudation hills ('puges') was discovered in the east of the Russian Plain at the end of the last century. These deposits were sometimes considered to be relicts of tills of the Pleistocene Ural...
