Figure 69. Structure formed by migrating, asymmetry-reversing bedforms with along-crest-migrating sinuosities.  The migration speed of the bedform is equal to the along-crest speed of the crestline sinuosities.  Bedform morphology is virtually identical to that shown in Figure 55, but in that figure the bedform is nonmigrating (perfectly longitudinal) and nonreversing.
