The morphology of the top tills’ surface of the South Polish glaciation (Sanian 2) in the centre of Wrocław.
S u m m a r y. South Polish tills surface in downtown Wroc³aw were mapped using 136 records of elevation of glacial tills surface. The unevenly distributed data were interpolated by kriging method. The investigated surface a reveals a prominent upward trend in the S–SW direction (from 95 to 114–115 m a.s.l.), average inclination is 15–20o. There are some evident irregularities in that trend, e.g., a 3–4 meters deep trim in the central part of map. Modern morphology of the top surface of glacial tills (Sanian 2) is a result of fluvial erosion after Sanian 2 glaciation. Some irregularities of the surface can be an effect of the brook character of that river. Position of the Recent Odra’s riverbed is directly connected with an old Pleistocene riverbed.
