Dip is the tan -1 of the gradient of a sloping surface. Open your eyes and mind and describe what you see in these outcrops. Flow layering is perhaps the subtlest type of surface to recognize. Write a concise report that summarizes your field observations and addresses the questions in the Procedure and Discussion sections above. Make sure to use consistent length units, and show all of your work.
