Mylor Slate Formation outcrop
Introduction
The photograph on this page of Mylor Slate Formation outcrop by Jonathan Wilkins as part of the Geograph project.
The Geograph project started in 2005 with the aim of publishing, organising and preserving representative images for every square kilometre of Great Britain, Ireland and the Isle of Man.
There are currently over 7.5m images from over 14,400 individuals and you can help contribute to the project by visiting https://www.geograph.org.uk

The tip of Restronguet Point comprises outcrop of the Mylor Slates Formation, a group of siltstones and slates of Devonian age. They are obviously hard here, because Caloplaca lichens have found a good substrate and developed fine colour. If rock is too soft, the whole lot weathers faster than the lichen can grow. It made me happy to see this, as I was reminded of the hard rocks of Wales, and it was compensation for crawling through a web of mooring lines.
