Despite this we did manage to get to Godrevy on Cornwall’s north coast for a day out. It was quite breezy but warm enough to walk comfortably and to sit and enjoy the views across St Ives Bay. This photograph of Godrevy Lighthouse tries captures theses conditions with the wind whipping back the top of the waves. I also processed a black and white version of the same image which provides additional emphasises the white water and the lighthouse:
Walking along the beach at low tide I took some detailed shots of the cliff face. What interested me was the seemingly abrupt transition from slates to mineral veined mudstone which shows on iGeology as a boundary between the Mylor Slate Formation and Porthtowan Formation.
As I understand it, slate is a metamorphic rock formed from mustone and shales sediments that been subjected to heat and pressure. There is certainly evidence of intense folding in the cliffs at Gwithian Towans which suggests that the Mylor Slate Formation sits above the mudstone layers of the Porthtowan Formation, although I find it hard to visualise this process when simply looking at the cliffs.
Another feature that caught my eye was sand patterns at low tide. I partcularly like the dark streaks that are formed by the retreating sea water:
Then there are patterns that can be viewed from the top of the cliff:
Finally, a couple of shots of the marram grass, an adder spotted near to the car park and the seals in Mutton Cove:
