Cirque overdeepening in the High Tatras Abstract: The High Tatras are currently an unglaciated mountain range with distinct glacial and periglacial shapes, as they were among the most glaciated mountain ranges during the Pleistocene. This allowed the formation of glacial cirques in the valley heads, which nowadays serve as ideal paleoenvironmental indicators. The aim of this work is therefore to determine the extent of cirque overdeepening in the Slovak part of the High Tatras and to establish the relationship of cirque overdeepening to standard morphometric, positional, and environmental characteristics of cirques. Based on the current digital elevation model (DEM), cirque edges, steps, and foot of cirque walls were defined and the values of morphometric parameters important for the construction of longitudinal profiles (k-curves, c-curves) were determined, thanks to which the overdeepening of the cirques was determined. The average value of the overdeepening of all the cirques according to the k coefficient was 0,85 (ranging from 0,51 to 1,46) and according to the c coefficient it was -0,97 (ranging from -0,11 to -2,96). The resulting inventory of 110 cirques was therefore used to analyse the relationships of the overdeepening coefficients to the above characteristics among themselves. The values of the...
