| This cliff face in the Coconino Sandstone along the South Kaibab Trail consists of massive sedimentary beds that display large-scale cross stratification (or crossbedding). Large-scale cross stratification like this can be found forming today in areas with migrating sand dunes such as in many world's large desert sand dune fields (like the Sahara or Arabian Peninsula) or in coastal dune fields on barrier islands (like those on the Outer Banks of North Carolina). |
