Following a recent post on Malham a couple of weeks ago where I uploaded some photos of a limestone pavement, I had numerous queries asking what it was, how it was formed and if I had any more examples.
Limestone pavements are formed when glaciation has scraped away the earth covering and left a slab of limestone exposed to the elements. Rainwater contains a mild acid and this dissolves the limestone and over the millennia cracks or deep fissures are formed. These are called ‘Grykes’ – and the slabs are called ‘Clints’. Together they make up the ‘Pavement.’
As the geology of the Yorkshire Dales is mostly limestone there are several areas of these pavements. As you can imagine they can be very slippery especially when wet and many a walker has slipped and had a leg trapped or broken.
Here are some more photos of some taken from Southerscales and show Ingleborough mountain and Whernside mountain in the distance.
