At Whitstable Harbour gabions have been put to good use in the construction of a remarkable feature. Approaching the construction I could see an intriguing pale line across the darker pebbles, very reminiscent of the pale lines of empty oyster shells that I had just been seeing on the pebble beaches between the breakwaters. Closer inspection proved the pale line to be a symbolic tide line of man-made decorated ceramic pebbles. The feature is known as the Deck at Dead Man’s Corner and is supposed to resemble the bow of a ship, the wall a pebbly beach, and the vertical timber structures are made to the same specification as the groynes along the shore. The ‘tide line’ is a key feature of white ceramic pebbles set into the face of the wall. These were made by local people during a series of public workshops and classes held at the Community College Whitstable. The whole structure comprises seating and a stage built in 2011 for gatherings and events.
The beach at Seatown in Dorset comprises a series of steep pebble banks. You can see how far up the shore the last high tide has been by the line of natural debris extending along the shore parallel to the water’s edge. On this occasion the strandline was almost entirely made up of dried red seaweed which contrasted well with the pebbles. Quite a number of white cuttlefish bones rested on the weed. I am fascinated by their beautiful structure. For some reason, the shape of the more concave surface (as in image 5) always makes me think of angels.
The shingle shore at Whitstable in Kent is protected by massive wooden groynes or breakwaters. At the time of my visit, the tide was high and the flint and other mostly worm-holed pebbles were steeply banked. The flat top of the beach was stabilised by vegetation with pink and white valerian and yellow ragwort the most colourful flowers. Pale bands of white empty oyster shells (mostly the rock oyster Crassostrea gigas) were high, dry, and dull on the shingle between the groynes; while lower down splashed by waves or heaped up against the wooden sea defence structures was a great variety of other empty shells including winkles, cockles, mussels, limpets, slipper limpets, whelks, netted whelks, Manila clams, and sting winkles. These were jumbled up with wet and dry seaweed, horn wrack, small pieces of driftwood, and flotsam. There was a marked contrast in the appearance of the shells and stones between the water’s edge where the wet shells were brighter and more colourful and the upper shore where everything was dry.
Broughton Bay is a wide sandy expanse on the north shore of the Gower Peninsula in South Wales, facing the Loughor Estuary or Burry Inlet. A small promontory called Twlc Point at the western end of the beach has an interesting geology with an exposure of Hunts Bay Oolite from the Carboniferous Period. I have written about these strata in earlier posts such as:
On this particular visit I was content to appreciate the way that pebbles of many types and colours on the upper shore were clustered around outcrops and boulders of the limestone which were often pink-tinged and sometimes fossiliferous.
