ENTRANCE INTO BADNJEVICE  CANYON- VIEWPOINT

     

PROLOŽAC MUNICIPALITY

Canyon through hard but distinctly tectonically fractured and karstified carbonate rocks of Mesozoic age. Along with tectonic discontinuities in the rocks, the rock avalanches are formed that reach the very bed of the river. This material is then rounded off and carried downstream in the form of gravel
