By doing this, you will unravel the geologic history recorded in the rock record, just as geologists did hundreds of years ago, and still do today. An earlier current-formed ripple set (at bottom of slide) was later modified by a second ripple train migrating at right angles to the first.Crests of the first set are preserved in the troughs of the second set, hence, the ladderback appearance.While this may sound questionable at first, keep in mind that we also accept the Law of Gravity with out direct proof.
After all, it is possible that rock layers can be disturbed, overturned, and altered in both natural and unnatural ways.
Keep these principles in mind as you progress through the rest of the activities in this assignment.
