Key Features

This sandstone rock contains sand grains that were transported by wind or water. The sand grains accumulated in fine layers or laminations on ripples. The fine lines on the face of this sandstone form a sedimentary texture called cross lamination, commonly associated with ripples. The orientation of the laminations indicates the direction of sediment transport in the flow regime.
