Examine the strike and dip of the rock units on the Devil's Fence geologic map in Figure 6.21. Draw multiple large arrows on the map, pointing in the direction of dip on several rock units. Do the rock layers located near the center of the map in Section 14 dip toward the northwest or southeast? The same rocks in Section 14 are also found in Section 18. Do the rocks in Section 18 dip toward the east or west? What is the approximate angle of dip of the units in Section 18?
1. Draw a dashed line representing the hinge line of the large geologic structure that occupies most of the map. Label the hinge line. 2. Are the rocks getting older or younger farther from the hinge line? 3. Is this geologic structure a plunging anticline or syncline? 4. Provide two lines of evidence that support your answer to Question 8.
On the map in Figure 6.21, write the word oldest where the oldest sedimentary rock unit is exposed at the sur-face and the word youngest where the youngest sedimentary rocks occur.
