A. Use a protractor to plot a strike and dip symbol at each station on the map where this information was measured. Write in the specific value of dip. B. Plot the lithology near each observation station, using standard geologic patterns. For shales or siltstone, make "grain" of pattern parallel to the strike bar to enhance the orientation of layering. C. Sketch in lithologic contacts (boundaries between layers). Project these contacts parallel to strike (i.e., parallel to the long bar of the strike/dip symbol)
