• 'The southern slope and the ridge are very strongly karstic, and the hill is composed of very steep, in places almost vertical Mesozoic formations. The first of these are Anisian dolomite in the north, which is followed by Callovian Cornbrash limestone (according to recent studies: Pliensbachian (Lower Jurassic) and then Callovian layers), then Lower and Upper Malm limestone, then a sediment hiatus in which a bauxite formation is intercalated; finally, Lower Cretaceous rocks on the southern slope of the hill. Here and there red clay containing bone remains fills the vertical clefs of the system of faults marring the hill.'
