Dry stone walls are a feature of the Gower Peninsula in South Wales, exhibiting many types of local rock, sometimes with fossils. The unevenness with which the rock surfaces are colonised by lichen depends on the composition of the rock, and the length and degree of exposure of each stone to the elements. These walls may collapse when people try to climb over them. The reconstructed wall will not always be exactly the same as before. The stones can therefore have an uneven coverage of wear and lichen.

I could look at this photo for hours. What a find.

Love your stone wall and limestone exposure photos from Gower, they remind me of my many similar photos of mine of the Burren of Co. Clare and the Aran islands in the west of Ireland! Can’t wait to see more! Just also wanted to mention a friend of mine resident near Gower who has recently self-published a new book on the hydrology, geology , geomorphology, and other associated -ologies of Gower which you may be interested in given your vast range of natural science interests.
It’s called: All Our Own Water : Landscape evolution, caves and hydrogeology of Gower, by Peter Kokelaar ISBN10 1399903357 ISBN13 9781399903356 – currently it’s showing as not available but I think I can get a copy to you if you’re interested. His website is here: https://kokelaargower.com/ and an overview of the book here: https://www.earthsciencepartnership.co.uk/newsfeed/all-our-own-water-landscape-evolution-caves-and-hydrogeology-of-gower/

Walking slowly allows me to notice the details – and there is always something new to see with every step along such extensive dry stone walling.

Thank you, Paddy. I noticed the similarity of geological features with the Burren too. I was surprised. People do not usually associate Gower with the Burren. Thank you also for the information about the book by Peter Kokelaar – I have been meaning to mention it on the blog myself. I have already purchased a copy and it actually has one of my photographs in it! It’s a great book full of fascinating information.
