This wrinkle ridge crosses through a mound of layered material that's been exposed by erosion. This observation poses an excellent opportunity to look at the internal structure of a wrinkle ridge. We can compare the topography and internal structure of this wrinkle ridge at this location to exposures in other terrain to see if the local bedrock has a noticeable effect on ridge morphology or growth.
The layers also represent stratigraphic markers that we know were once continuous. Examining faults that cross-cut and offset layers can yield good information about the amount and direction of movement that took place along that fault.
