3) Study Figure 6.20 using the link below.
It shows a sedimentary structure called a cross bed. These cross-bedded Jurassic Navajo Formation aeolian sandstones are in Zion National Park, Utah. In most of these layers the cross-beds dip down toward the right, implying wind direction from right to left during deposition. Note that one bed dips in the opposite direction, implying an abnormal wind direction.
For this exercise, search the internet for another image of cross beds. Copy and paste it in your document (no .heic files).
Report on a) the location of these cross beds (State, country, and other details) and b) the direction that the wind or water was moving to make these cross-beds.
If there are two directions, explain both and make clear which beds you are referring to.
