The coast in this park is lined with jagged rocks and steep ocean cliffs. The rocks are shaped and formed by the continuous crashing of the waves. These rocks provide an array of tide pools while the tide is out.
Rocks The rocks of Salt Point are sedimentary, mainly sandstone. All of these rocks are tilted, exposing older rocks. The rocks at the north end of the park's coast are younger than the rocks at the southern end. Salt Point is named for the
tafoni where the ocean water crystallizes in the honeycomb like crevices. This tafoni is caused when the salt crystals interact with the sandstone making parts of the sandstone harden while other parts soften.
Deep-sea fans The layers of sedimentary rock show evidence of a
deep-sea fan. A deep-sea fan is caused when there is dense, turbulent
sediment filled water flowing down a
submarine canyon. This highly dense water is called a
turbidity current. Something that may cause a turbidity current are
earthquakes or storms that create a submarine slide. When this sediment filled water leaves the end of the canyon it spreads out in a fan like shape. The sediment is thinner and thinner the farther away the sediment is from the submarine canyon. All of these layers of sedimentary rock are created thousands of feet below the ocean's surface but now the layers are visible above the surface of the water. This is because the
Pacific Plate and the
North American Plate are moving against each other; since the oceanic plate is lower, it is being forced below the continental plate in a process called
subduction. While the oceanic plate is being subducted, the continental plate is scraping off the top layers of the oceanic plate slowly bringing them to the surface. == Activities ==
