Williamson Park in Lancaster was built on the sandstone quarries from which much of the stone for the city was cut. In the 1860s it was landscaped by mill workers left unemployed by the "Cotton Famine" of the US Civil War.
The park has many outcrops of "Pendle Grit" sandstone overgrown with ferns and ivy and covered with lichen. I was surprised to see a band of softer rock, shale I think, between the two thick beds of sandstone, something I had not noticed before. See webapps.bgs.ac.uk/Memoirs/docs/B01527.html
