Low Tide Surfers with visible Reef

This is a view from a high angle taken on a partly cloudy day. The sun is overhead. Some chaparral brush is seen growing out of the sand. A man with a cap walks by on the beach.

Watch closely, and you can see the low-tide reef exposed when the clear water recedes. The ocean water calmly laps overtop the rock, then ebbs away.

If the video player window is maximized, you can see about ten surfers taking advantage of the medium-sized swells.
