Describe the folding features visible on this geological map, including type, orientation, and symmetry.

Step 1: Describe folding on the map.
The geological map displays folded sedimentary rock layers. Both anticlines (upward-arching folds) and synclines (downward-arching folds) are present. The folds are plunging, meaning their axes are inclined, and they appear to be relatively open and symmetrical. The fold axes generally trend in an east-west direction.
