Is Cefn Bryn made of Old Red Sandstone too? Wonderful patterns.

Yes, you are right. Cefn Bryn is made of Old Red Sandstone. This is a useful link to the details https://www.geolsoc.org.uk/GowerTour2,
The rocks in this period are extremely variable because of the frequently changing conditions in which the rocks were laid down and differences due to the locations, The Orkney Eday rocks look different from the Gower representatives for the same period. I will be posting some more pictures from Waulkmill Bay later, showing some lovely pink and white patterned rocks in the same place as the ones in this post.

Looking at these as if from the distance of eg the Space Station, these seem like large-scale arid geological features. Interesting!

Yes, RH. They do look a bit like dried up rice paddy terraces on Chinese hillsides.
