The pebbles are mainly flint and chert from the Cretaceous and Jurassic rocks which make up this stretch of the Heritage Coast, along with bunter pebbles, possibly from Budleigh Salterton, although no universally accepted geological theory has been formulated to explain the mode of transport. (Yes. With less wind resistance between the two bikes, the racer on the trailing bike flies right by. Alternatively, it could be because the wind and wave front are frequently at an opposing angle to the prevailing wind, generating short periods of longshore drift in the landward direction. First, it was inhabited by early natives who came there to camp out. The beach is steep, showing a clear storm beach.

How does beach material vary across a storm beach? Knowing when and where landforms evolved provides cues to archaeologists searching for artifacts from historical people in the area. At the turn, longshore drift continues in the original direction, but its energy is dispersed, lost as the wave refracts and the current spreads, leading to deposition on the sea bed. In conclusion, the California Central Coast is amazing for an earth scientist to come study and observe the various coastal landforms that are present. Like spits, these usually form due to the action of longshore drifts. This is particularly the case where constructive waves are prevalent or where there is an abundant amount of beach material supplied. as a source of sand for beach nourishment, for shingle dredging for construction material.
