Tulip?

I think I have posted some of these before.  The fascination endures, so here’s another.  Who would think to draw this?  Why, the receding ocean, of course, pulling the light colored sand away and revealing the dark.  Marvelous.

Walking on the beach, with the feel of the wind, the shout of the waves, the scent of the seaweed, the strew of the stones, the insistent cawing of the gulls: it all restoreth my soul.
