Dendritic Drainage patterns


On our first walk along Costa Adeje beach in Tenerife, I noticed these fascinating patterns on the volcanic sands, at first I thought I was looking at impressions made from seaweed but soon realised I was looking at something else. I took a few pictures when passing and the following day while my wife was sunbathing I spent hours taking over a hundred digital pictures. These Dendritic patterns are caused when the sea drains back out to sea, the patterns are washed away when the tide returns. The rest of the week there was no marking on the sand even when the tide was retreating, I suppose the conditions have to be right. The beautiful patterns to me looked like branches of forest trees and some looked like leaves from an abstract painting, especially when viewed upside down.

The pictures above are closer to the original colours, although I have had some fun enhancing the colours of the sand on some of the larger picture shown using Photoshop plug-in "Aurelon-CoCo" to show the detail of the markings.
