Marine terraces at El Granada Beach

View on map:37.504338°N 122.481412°W

Comments

The wave cut terraces were formed about 100,000 years ago when sea level was much higher. If you look to the east you can see the wave cut terraces with higher ones that are dissected by streams. The terraces to the west of the airport are higher because of uplift along the Seal Cove Fault.   

Description


Marine terrace

A marine terrace, coastal terrace, raised beach or perched coastline is a relatively flat, horizontal or gently inclined surface of marine origin,[2] mostly an old abrasion platform which has been lifted out of the sphere of wave activity (sometimes called "tread"). Thus it lies above or under the current sea level, depending on its time of formation.[3][4] It is bounded by a steeper ascending slope on the landward side and a steeper descending slope on the seaward side[2] (sometimes called "riser"). Due to its reasonably flat shape it is often used for anthropogenic structures like settlements and infrastructure.[3]
