                                                               Wave Ripples  Wave ripples are characterized by symetrical profile to the wave crest.This is taken in July 13th 2011 in Eric's study area where Pa.6 is interpreted as wave influenced, fluival-dominated delta front deposits.                                                                2-D Current Ripple Picture was taken in Summiyah's area. Relative straight crests make them 2-D ripples. The asymetrical profile is diagnostic of current ripples.                                                                 3-D Current Ripples Picture was taken in Dan Fix's study area in Henry Wash. The sinous crests make them 3-D ripples.  Fluival channel and floodplain deposits are interpreted in the upper Ferron Sandstone.                                                     Current Ripple Cross Lamination Current ripple cross lamination shows a unidirectional dipping pattern, which indicates the paleoflow directio
