Specialized folding structure: • Synclinal Ridge – a syncline that is resistant to weathering and erosion may form a ridge • Example: Sideling Hill
Folding • Synclines and anticlines can be plunging • Plunging means that the axis of the fold is not level (horizontal) • Unique landforms: From Schmidt, Martin F. 1993 Maryland’s Geology. Tidewater Publishers, Centreville, MD.
