Cechy rozwoju i zaniku lądolodu warciańskiego w środkowej Polsce
The South Great Poland ice-sheet lobe representing the Warta Glaciation stretched from the Warsaw-Berlin pradolina that runs along the S2nd parallel (100 m above sea level) to the Wieluń Upland (272 m above sea level) in south (SI°N). The lobe was halted by topographic barriers of the Ostrzeszów Hil...
