Natural patterns and textures in the sand on the beach at Rhossili Bay in the Gower Peninsula, where temporary flows of freshwater across the sand have created smooth sinous lines and organic shapes like ferns and trees. Recorded 27th October 2010.

These are among the most intriguing patterns you’ve posted. (14) reminds me of celery stalks or trees, and (12) also strikes me as botanical. Have the wind and sand learned tricks from the plant kingdom, or vice-versa?

I am discovering great coincidences in shape, pattern, and texture in subjects across the span encompassed by the natural sciences. The tendancy to the dendrodic form (as in photo 14) is one of the most commonly found. I am sure there is a plausible explanation – I just don’t know it yet. I am gathering together a collection of images to illustrate these serendipitous forms. One example, that is easy to comprehend is the variety of ripple patterns in water which create similar designs in soft beach sediments, and are also preserved in rock.
