More rocks from the Eday Group of the Old Red Sandstone Supergroup, Devonian age sedimentary strata on the west side of Newark Bay in Orkney. The difference between the appearance of the dry rocks and the wet ones is always striking. I loved the contrast of the black lichen growing on the orange-red boulders, and the vibrant yellow-green of the young seaweeds. White campion was growing on the cliffs here. On the pebbles of the shore there was another dead seabird and also a hollow of finer pebbles that looked like an abandoned bird nest. I am still wondering what the strange porous object was that I picked up – some sort of sponge I guess, all dried out and reduced to its fibrous matrix.
