The second of the series of sand ripple photographs taken on a single walk across the shore at Broughton Bay on the north coast of the Gower Peninsula in South Wales. These natural patterns vary a great deal according to location. This is due mostly to the way the tide ebbs and flows along the Loughor Estuary and out into Swansea Bay and the Bristol Channel. The flow of water responds to the topography, the shifting sand banks, rocky promontories, and underlying remnants of the fossil forest. Wind and currents affect the ripple designs too. The way they appear in the pictures is also affected by the angle from which they are viewed, how wet the sand is, the amount of cloud cover, the height of the sun in the sky, and the time of day. So as the weather changes and the day progresses the same patch of ripples might appear very different.
