Virtual Outcrop Model of outcrop section Fortet North. Fortet is a paleokarst breccia outcrop at the southern end of Wordiekammen. At Fortet North the western section is characterized by stratified sedimentary breccias deposited "inversly" onlapping to the paleo-cave ceiling. Towards the east of the stratified breccia we find chaotic breakdown breccia which are truncating the stratfied breccias. The chaotic breackdown breccia resemble a second phase of dissolution and collapse of a paleokarst system.
