You remember from the previous picture how much the sand was giving in. And then suddenly, in the middle of the beach, there is this formation. Almost like a cliff of sand. How do you explain that?

You would expect the cliff to have broken down and be like a gentle smooth slope. The rest of the beach was. Just in this portion there was this cliff. To test out whether there were rocks underneath, I started breaking down one small portion of the cliff at the end. There was nothing other than sand. The sand there did feel a little more wet.

Why this complete anomaly in the geographical formation?

Can anybody help me?
