This photo was taken early in the morning on the 1st of April on Chatham South Beach at low tide. As the ocean recedes the water seeps out of the sand bank and on the flats can lead to these types of patterns which to me look like thick 3 dimensional brush strokes.
I took photos in 4 places, all of which are in my Seascape Gallery. I hope you like this one.
