On the other hand, hypotheses relating the subsidence to karst or pseudokarst
processes in the underlying sedimentary sequences (Tertiary or Cretaceous, cropping not far away) cannot be ruled out.
Geology and Speleology were yet to develop as sciences, yet Lewis & Clark made significant observations of karst, pseudokarst
, and paleokarst features.
By this way, the castellated rocks are formed with all other shapes and forms such as the pseudokarst sinkholes (Zaruba et al., 1966).
The slow creep movements (due to gravitational disintegration) occur mainly above the edge of thick-bedded sandstones in form of inclined blocks, rock towers, pseudokarst sinkholes, linear depressions and fissures.
Numerous forms of selected weathering and of removal of rocks, often of pseudokarst character can be found.
The forms of block slope movements, pseudokarst phenomena and small castellated rocks occur at some places (Balatka and Sladek, 1984).
GEOLOGICAL CONDITIONS IN THE KNEYNE-CERTUV MLYN AREA, DESCRIPTION OF GEODYNAMIC PHENOMENA (PSEUDOKARST, LANDSLIDE-PRONE AREAS)
Fissures of the N-S fault system on the top of the mount Certuv mlyn, widened by erosion, form a several-metres deep morphological depression with presence of pseudokarst features.
