National Natural Landmarks
Gay Head Cliffs
The colorful Gay Head Cliffs, resting upon the continental shelf, yet detached from the mainland, rise to 150 feet above sea level and provide a cross-section of pre-glacial sediments overlain by fossil-bearing sands. It is the most extensive and scenic exposure of Cretaceous and Tertiary formations on the New England islands and Cape Cod.
