California coastal erosion
This region of the California coastline is lined with coastal bluffs that have been shaped not only by runoff from rain, but also by wave- and wind-driven erosion. This photo from Pescadero State Beach displays an example of a bluff undergoing erosional processes. Water from the ocean, delivered in waves, can overtop some of these coastal bluffs. As water runs off the bluff from ocean waves, it erodes away sediments and slowly carves unique shapes into the surface of the bluff, creating features such as this series of gullies.
