Subtle colour transitions and delicate branching patterns characterise the low relief natural sculptures in the fine clean sand shown in this photograph. It was one of many taken on the shore near Picquerel Point at Grand Havre in the Channel island of Guernsey. The dendritic patterns have been created by sea water draining down the beach as the tide recedes; and this has led to a sorting out of particles by size, weight, and colour. The darker sediments that outline and emphasise the design may be organic remnants or different darker minerals. These patterns are the best of their type that I have seen – perhaps due to the very fine sand. They look like pencil sketches. I am definitely going to frame some of the images.

incredible how much like a sketch this looks, as you say Jessica. To me, it looks like the old-fashioned way of drying sheaves of straw standing in a field.

I see what you mean, Adrian. I tend to think of them as fantasy forests, alien trees.

Amazing – difficult to believe this isn’t a drawing. Even on closer inspection it resembles drawing. Fantastic 🙂
