This morning I drove Clare to her study group in Dinas Powis, then drove to Penarth, for a walk on the foreshore from the path at the end of the barrage. It's an unusual beach, interesting due to the geological strata in the cliffs above. In some places marl layers take a grey or green colour due to differences in the minerals leached by water out of deeper rock strata. But red limestone beds of crumbly stone of the Upper Triassic era predominate, shot through with layers of pink alabaster. Said to be one of the largest deposits of its kind in this particular stratum of rock.
After lunch, I drove Clare to the Heath hospital for another post operative eye check-up, then I returned home and walked around Pontcanna. Today, I picked up fourteen assorted items of rubbish, just six from the beach, including a five litre plastic 'can' washed up by the tide. I could have collected more, but hadn't taken a bag with me, maybe just as well, as I would have ended up being late, and not having time to enjoy the geology.
