breached anticline

breached anticline
   A structurally-controlled landscape or landform typically underlain by sedimentary rocks in which an anticline crest has been eroded such that the former crest has become a canyon or valley flanked by inward-facing erosional scarp slopes or cliffs and outward-facing dip slopes. When used as a landscape term, the associated landforms include cuestas and strike valleys.
