Introduction
The photograph on this page of Rocks on Froggatt Edge by Penny Mayes 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 grit stone outcrops on Froggatt Edge display a variety of colours. Presumably some of this is due to lichen growth but I wonder if the black is down to air pollution from the steel mills in nearby Sheffield.
