Pancake Rocks are irregular in shape and the formation of their layers, and are surrounded by blowholes. The rocks are limestone country, and each of the layers are a combination of resistant bands of limestone that are separated by thin, softer, mud-rich layers. This layering is common to limestone and it is called stylobedding.
The cause of stylobedding is believed not a natural formation,
but by compaction. The blowholes are also the contributing factor.
The erosion by the water, wind, and salt spray have all created the
pancake layering.
