FIG. 45.  Structure formed by oblique bedforms with pseudorandom plan-form geometry.

RECOGNITION: This structure is similar to that shown in Figure 43, but the pseudorandom plan-form geometry adds complexity and causes scatter of the bounding-surface poles.  Recognizing that the complexity arises from spatial differences in bedform morphology, rather than from temporal differences in bedform morphology or behavior, requires three-dimensional exposures that include extensive horizontal sections.

ORIGIN: This structure differs from that in Figure 43A only in having a more random plan-form geometry.
