This is the very same rock fin (‘Unshore Rock’) that I photographed as Unshore Rock Fin, Northcott Mouth; I had a memory that I had photographed it before. This was taken in November last year; although taken near midday it was also fairly near the solstice with the result that the large cliff known as “The Black Wall” to climbers was obscuring the sun from hitting a substantial section of beach such that the sun was only just catching Unshore Rock creating this quite dramatic lighting effect.
From above you can clearly see the horizontal fault lines so typical of this section of coast leading out to sea. These were formed in the Variscan Orogeny nearly 300 million years ago.
I wouldn’t be in the least surprised if my vantage point here is now at the bottom of the cliff after the rock falls along this section this winter.
I will post one more dramatic photo of this fin soon.
