Ripple beds, Wren's Nest (close-up)
This close-up of the ripple beds in the Nodular Limestone Member shows the ripple patterns created by wave action when these rocks were deposited (before being folded up at this angle). This indicates that the surface of the sediment was near the wave base of coastal waters, i.e. that part of the seafloor which is never or rarely exposed but is always within reach of the turbulence of waves. While many of the cracks will be due to recent weathering, some of them may originate as sun cracks from occasional exposures of the sediment at exceptionally low tides.
