This work also researches geomorphologic traces of Pleistocene glaciations on area of highland massif of Ĉvrsnica and Ĉabulja ridge in the central part of The Dinarides mountain range. With the surface of 513, 45 km2, it covers the area between the canyon valleys of the river Doljanka and The Neretva river on the north and on the east, and on the east, mountain ridges on the west (Vran and Libo) and the plateau of Brotnjo on the south. The key structures and faults have the Dinaridic orientation line. In litho-logical system it is mainly karst, carbonic layers of Mesozoic origin (limestone, dolomites). Apart from the geological and structural features; glacial, karst and slope processes have influenced geomorphologic formation of terrain. At high range mountain area, the network structure of terrain is predominant, with the chain of elevations (ridges, hilltops), hollows (karst sinkholes, karst depressions) and plateaus. That same terrain of pre-glacial era is exactly the one that is good for accumulation of snow and ice, if climatic conditions are right, which is in fact, creation of meltdown erosion. Based on the analysis of morph metric parameters, reconstruction of the climate during the pre-glacial meltdown and areal distribution of glacier morphologic forms, it can be presumed that maximal area of meltdown erosion is around 200 km2, which covers the top part of mountain range massif and ridges. It has been determined that there are three types of glaciers: cirque, plateau and valley types. As the outcome of the exoration formation in recent terrain shapes it was determined that there are 26 well-preserved cirques. The largest number of cirques is developed on the slopes of ridges of north exposition and it has smaller surface. Cirques of south orientation are larger, formed in karst depression predisposed by faults. Plateau glaciers had regional features, and its direction line and range is determined by ice feed, as well as by stretching of the ridges. Established glacial valleys in upper part have characteristically U-profile shapes, and its length and the direction line is determined by layers of accumulative glacial sediments (stratum, glacial-fluvial sediments). Plateau glaciers had regional features, and its direction line and range is determined by ice feed, as well as by stretching of the ridges. By analysis with granulotmetry of accumulated layers on certain, equally disposed locations in major cases, relatively low level of the roundness of grains is present, with almost two thirds of larger particles is gravel and relatively low level of division of material is also present, which denotes sedimentation by ice (strata and glacialfluvial fans).
