Nature overflows with patterns, whether growing branches, ripples in a pond or the fan of petals on a flower. Many are images of some sort of tension. None is “perfect”—such an impossible human concept—but many tend in that direction because that is what so often works in nature. Seeing these patterns is humbling, a continuing lesson is the beauty the world is—exactly as it is with nothing added.
The sand, wind and gravity create the patterns in the dunes. Add light and shadow and the images become works of art.
I especially love seeing how wind drives patterns in both the sand and the clouds. The similarities are striking, the differences fascinating.
Still Learning To See 
Great eye, John. I enjoy your appreciation of nature. Ludington is beautiful, isn’t it?
Thanks. Yes, so nice to be back on “The Big Lake” as we have always called it.
