Eroding sea cliffs at Cape Elizabeth

Narrow beaches and steep cliffs rim the central coast of Washington, from Point Grenville to the Hoh River.
Eroding cliffs at Cape Elizabeth These soft sandstones and siltstones are continually eroding and sliding. High winds erode the upper cliff face. Erosion at the base of the cliff occurs during winter storms.
Sea stacks at Point Grenville This sea stack at Point Grenville is composed of volcanic material that was ejected onto the sea floor as lava 45 to 50 million years ago.
Cobbles, boulders and sand on the beach at Cape Elizabeth Boulders and cobbles can be found near Cape Elizabeth. Many beaches along the central coast are made of sediment from eroding sea-cliffs. Because there are geological differences in the cliffs, beach textures vary from fine sand to large cobbles.
