Figure G-15 contains five geologic maps, each of which contains folded strata. Fold a piece of paper to help you visualize each fold’s shape and orientation, then draw crestal and/or trough traces on each map. Use the appropriate symbol (see Appendix F) to indicate the type of fold (syncline or anticline), and indicate the attitude of the fold axis.

Determine the trend and plunge of each fold axis and write these in the space provided below each map.
