Although these flat expanses of bare limestone (such as at Moughton Scars above) are common in the southern part of the Yorkshire Dales, they are a very rare habitat both within the UK and globally.
Seen close up. it is easy to see why they are referred to as 'pavement'. The flat paving slabs or clints to give them their correct name are separated by weathered joints called grikes.
But more of that tomorrow.....
If however, you can't wait, you could have a look at what the Limestone Pavement Action Group have to say about the formation of limestone pavements. Their website is worth browsing and bookmarking for future reference.
