Interpret the depositional sequences of C and D. Are there unconformities? Are all rock units horizontal? Interpret each sequence of events. Interpret the kinds of Faults in E and F. Explain how you know what kind of fault it is. Discuss the footwall and hanging wall.

Determine the appropriate contour interval that you should use in MAP G. Then use this interval to contour the map. After contouring describe what the area is like. For instance, is it a river channel? A box canyon? A mesa, with cliffs?
North MAP G
In diagram H what are is the geologic history? Interpret the rock sequences and determine which feature came first and how you know that.
