Remarks on the Genesis of Subglacial Channels in Northern Poland

Michel Pasierbski
The origin of the majority of subglacial channels and similar valleys in Nothern Poland, taking in account their character and differenciated shape (narrow, deep, long and curved) is connected with erosional activity of subglacial waters. But the author based on several examples shows, that some of these channels have a more combined genesis, when the main factor has been the inland ice (narrow, small ice tongues).
