These photos show the only time I have seen ripple patterns in the tidal mud of the bank of the River Thames. I cannot say whether it is actually a rare occurrence because I do not visit the location very often. What makes these ripple patterns especially interesting is the fact that they are clearly layered, with a finer blue-grey sediment being deposited on top of the normal mud. I am wondering what special phenomenon resulted in this dual deposition on the textured surface of the river bank.

It reminds me of cuneiform writing. The patterns, I mean. And I like the color overlay however it occurred.

This are curious patterns they remind them of the patterns you get on iron man-hole cover (the square ones).

Nature is a strange thing and some times we never know the true reasons. They remind me of fossil river beds.

Something like this, Claudia? I photographed this cuneiform writing at the British Museum.

Something like this, Emma? I photographed this outside my home just now.

I saw fossil river beds in Canada. These pictures are from Joggins Fossil Cliffs in Nova Scotia and Cape Enrage in New Brunswick respectively. You can see the relationship between the rocks and the sediments on the Thames river bank.

I have never seen them in real life only on TV. Must be good to see the real thing. I suppose that’s why trees are my passion they are all around me.

Yes, exactly. In college, one million years ago, I took a class in Archaeology to fulfill a requirement. We learned about writing systems of the ancient world and cuneiform really took hold of me. I also enjoy it even more now, because I understand the feeling of making this kind of lettering in clay, since I have been working in clay myself. I envision myself a scribe in a previous life, maybe?

And it is fascinating to put present-day Nature in its evolutionary context through a study of rocks and fossils, don’t you think, Dick?

Working with clay and with words seems to be in your genetic make-up, Claudia.

Maybe so. I’ve always liked words – clay I didn’t find out about until I was an adult (I admit to being unaware that contemporary people were making pots, that you could do that, until I was maybe about 20? we just had nothing like that where I lived, growing up). But the subject of clay items has always fascinated me.
