Rock Strata from Kimmeridge Cliffs – Part 1

Detail of cliff strata from Kimmeridge Bay

The first selection of photographs taken at Kimmeridge Bay in Dorset, England, yesterday (27 March 2015) showing details of the natural patterns, textures, and colours of the rocks. The rocks are described as rhythmically inter-bedded blocky, organic-poor mudstone and fissile, organic rich shale.

Patterns in Rhossili Sand, March 2015 (3)

Silvery sand patterns at Rhossili Bay

One rainy morning I walked the coastal path along the terrace at the foot of Rhossili Down in Gower. Clouds shrouded the slopes of the Down above me. Ahead of me, Burry Holms and Llangennith Burrows were part concealed by mist. Below me, the tide was going out – far out. The sand on the beach was still wet from the waves and the rain. Slowly the cloud cover thinned and allowed a filtered light to penetrate. The pale light was reflected by the shore, high-lighting the sea-sculpted rows of ridges and ripples in gentle gleaming silver. A stream cascading from the height of the Down worked its way down to the beach, where it spread out in a fan of interweaving channels that cut across the parallel ridges on its way to the water’s edge. Coloured sediments carried by the stream tinted the silvery patterns and made them seem opalescent.

Natural patterns of dark streaks along the driftlines of a sandy beach

Natural patterns of dark streaks along the driftlines of a sandy beachDark streaks drawn into abstract designs by the swash and back-swash of waves sometimes decorate the succession of driftlines on the sandy beach at Rhossili Bay as the sea recedes. The blue tinge of the darker areas makes me wonder whether they are composed of comminuted fragments of blue-black mussel shells.

Natural pattern and texture in damp sand at Rhossili Bay

Natural pattern and texture in damp sand at Rhossili BayI never cease to be amazed by the new variations of natural patterns in the sand revealed with each ebbing tide on the vast sandy shore at Rhossili Bay in Gower, South Wales. These photographs were taken in March 2015 and add to the continuing documentation of the array of topographical changes that affect this wonderful beach.

Rhossili Tide Pool Ripple Patterns

Close-up photograph of reflected light on rippled water

It was a dull clouded sky after a morning of rain on Rhossili beach with an outgoing tide. Wide shallow tide pools on the sand at the base of the cliffs were luminous with reflected light. Where the breeze ruffled the surface of the water, the crests of the ripples appeared sharply green against the pale background, creating natural moving patterns that looked as if they had been painted on the surface with a fine brush.
