The geology of Parkinson’s Park is special. It sits, on the edge of the Chevin escarpment, just where a seam of millstone grit (that forms Whale Jaws Hill) meets the wide band of Guiseley grit. On this picture Guiseley grit is coloured orange, and the millstone grit is the band of pea green at the top left hand corner. The other areas of green around Guiseley are areas of glacial deposits.
You should just be able to pick out the cleared Netherfield factory site before the houses started to be built (which is off to the top left of the picture). Further pictures of the geology of the chevin are available in downloads from The Friends of Chevin Forest Park website.
