Marker Name: Cliffs, caves and arches . . . masterpieces in progress
Marker Text: As you gaze out over this view, you are seeing econs of nature’s continuing work. The erosive power of wind and waves constantly sculpt these fantastic rocks, creating beautiful cliffs, islands and beaches.
The sediment carried in water constantly grinds against the rocks, slowly breaking them down. As waves crash, the cracks and crevices are weakened and they break apart.
Notches form and enlarge into sea caves, and eventually into arches. Sometimes, the top of an arch collapses, forming a natural blowhole.
The most dramatic erosion happens during fierce winter storms, when waves exert great force on the exposed rocks. Only the strongest parts of the rock resist. Arches collapse and form columns called sea stacks.
