They consist of the westernmost Biščevci Blind Valleys, the central Sajevško polje Blind Valley and the easternmost Ivačevci Blind Valley. They consist of a "bottom" part, fully or partially covered by allogenic (flysch-derived) sediments or a karstified bottom in the case of Ivačevci Blind Valley (hydrologically non-active, relict), and a "slope with rim".
