Giving even more variety to this astonishing habitat are the cracks and crevices, known as grikes, in the limestone pavements. These fissures can be up to six feet [2 m] deep.
Vēl lielāku daudzveidību šim neparastajam dabas apgabalam piešķir neskaitāmas plaisas kaļķakmens bruģī, kuru dziļums vietām sasniedz divus metrus.
