In the northern part of the Podhale Region, nearly 100 years ago, Matkowski (1924, 1928) described gravels exposed in a quarry in Szaflary and considered them to be moraine sediments - Szaflar moraine. Romer (1929) confirmed this interpretation of the sediments. Later studies of Halicki (1930), Klimaszewski (1948, 1988), Birkenmajer (1976) and Birkenmajer and Stuchlik (1975) completely excluded the possibility of moraines in this area and showed that these sediments have are of fluvioglacial origin. Comparing the quarry's ranges due to exploitation, it was found that the authors could observe various deposits exposed during the progress of exploitation towards the west. In the profiles of trenches for new buildings to the NW from the quarry, clays containing sands and gravels and individual boulders and blocks of quartzite and granite with a diameterof0.8 to 1.2m were found. The exposed erratics exactly correspond to the description of the moraine by Matkowski (1924, 1928) from the quarry in Szaflary. In addition, in the recently drilled Nowy Targ PIG-2 borehole, similarly developed pieces were found at a depth of19.7-69.5 m. Combining archival data and new facts from drilling and exposures, a view can be proposed that, during the Southern Polish Glaciations, the Tatra glaciers reached the Nowy Targ Basin and perhaps the foothills of the Gorce Mts, which was already suggested by Rehman (1895), Zapatowicz (1913) and Matkowski (1928).

The northern part of Lubusz Lakeland is the area of a various relief, where are clearly marked morphological by varied Ośno-Sulechów Hills and a flat Torzym Plain, situated farther south. Both units are cut by deep valleys used by rivers and lakes. The relief generally arose at the end of South-Polish Glaciations. In the first stage, push moraine[Ośno-Sulechów Hills] formed of folded Paleogene and Neogene and Quaternary sediments. The extent of the vertical Cenozoic sediment movements presumably exceeds 250 m. On the Torzym Plain, there were much less disturbed Paleogene and Neogene sediments in the form of a big beaming folding structures. In spite of the lack of Paleogene and Neogene convincing evidence, it’s not possible to reject tectonic movements during formation Ooeno-Sulechów Hills and Torzym Plain. The younger glaciations modified earlier elements of this relief to a small extent. During the next stage of the South-Polish Glaciations [Sanian] very deep subglacial valleys were eroded, which probably were connected with the drainage system of central and northern Germany. The valleys cut out the subglacial zone of Ośno-Sulechów Hills and Torzym Plain to the depth of over 160 m b.s.l. Those valleys still existed during the next glaciations and interglacials, as indicated by fluvial and lacustrine sediments of Mazovian Interglacial age, as well as valley sandurs of Pliszka and Ilanka rivers originated during the Weichselian.
