Kimmeridge Rocks, posted on Flickr.
Last weekend I was in Dorset in the village of Kimmeridge helping out on one of my mum’s yoga weekends. In some spare time I walked down to the beach and, being a fan of rocks, decay and entropy, took lots of photos of the cliffs falling into the sea. Falling geologically that it. I didn’t actually see any of them fall.
Last time I went to Kimmeridge was in 1970 to look at the one oil well (now abandoned). The black shales in your photos are the reason the UK North Sea has so much oil. The Upper Jurassic Kimmeridge Shales has provided all the oil in the North Sea. The cliffs sometimes break out in spontaneous combustion.
Kewl!!
