- This paper is an answer to the polemical article Critical remarks on reconstruction of surface geometry of glaciers in the Polish High Tatra Mts. by Jerzy Zasadni in current issue of Przegląd Geologiczny. The criticism concerns our paper on reconstruction of surface geometry of the last glacial maximum (LGM) glaciers in the Polish High Tatra Mts. (drainage basins of Roztoka and Rybi Potok), published in Przegląd Geologiczny vol. 57, no 1, 2009. The main objections of our opponent concern on our reconstruction of equilibrium line altitude (ELA), ice surface geometry and paleoclimatic interpretations.We present a new reconstruction of ice surface geometry within the drainage basin of BiałaWoda during the last glacial maximum (LGM), including the part of a glacier previously omitted. The model of the glacier was made on the basis of detailed field mapping of glacial trimlines and analysis of digital elevation model (DEM) of the BiałaWoda Valley. The glacier surface area was found to be 37,61 km2. We found ELA value for AAR = 0,67 to be consistent with previously calculated average ELA value of 1430 m a.s.l. for AAR = 0.4, 0.45 and 0.5. In turn, some uncertainties concerning ice surface geometry in ablation area may be best explained as due to inaccuracy of geomorphological data, whereas the well-established ice surface elevation within accumulation area does not show any theoretical errors.We also show that glaciological parameters (t values along the glacier profile), questioned by our opponent, are consistent with glaciological conformities.We want to admit that paleoclimatic interpretations of paleocirculation presented in the ,previous paper was rather untimely.
