FIG. 73.  Structure formed by bedforms with sinuous, out-of-phase bedforms migrating alongslope.  This depositional situation resembles that shown in Figure 72, but here the superimposed bedforms are migrating alongslope rather than obliquely downslope.

RECOGNITION: This example is so similar to the preceding example (superimposed bedforms migrating obliquely downslope) that the differences probably could not be interpreted in natural exposures.

ORIGIN: This structure has essentially the same origin as the examples in Figure 46, except that in this example the superimposed bedforms are three-dimensional.
