forms have been identified at the hillside and the peaks.
The closed depressions occupy 5.0% and are developed on
slopes up to 40°.
Karstic, snow, glacial, periglacial and gravity forms
were mapped. The former includes karstic deposits,
dolines, glaciokarst depressions, caves and cave passages
projections. The karst deposits are situated in the areas
without slope and are mainly formed by mud that comes
from the dissolution of the limestone. The sinkholes are
depressions of 5- to 20-m wide and 1- to 5-m depth and
associated with gravitational deposits. The dolines are
closed and dominated by breakdown processes; thus, they
are mostly collapsed sinkholes. The glaciokarst depressions
are closed hollows of 600-m wide and 70-m depth located
