Gravitational disintegration of the Čertův Mlýn Mt. (Moravskoslezské Beskydy Mts.)

Silesian Unit represents a geological structure which is highly affected by deep-seated gravitational slope deformations on many places. One of famous examples of spreading of a mountain ridge is located on the elevation of Čertův Mlýn Mt. in the highest part of the Moravskoslezské Beskydy Mts. Besides typical displays of double ridges, crevice-type caves, counter-scarp slopes and shallow landslides there are huge tectono-gravitational block deformations. Some manifestations of gravitational spreading were dated to the period of quite young Holocene (Subboreal-Subatlantic). Geophysical measurement revealed that gravitational deformations prograde to the depth even in areas without observable topographic manifestations.Silesian Unit represents a geological structure which is highly affected by deep-seated gravitational slope deformations on many places.
