Limestone cliffs at Gordale Scar

I took this picture standing in front of the waterfalls at Gordale Scar (near Malham, North Yorkshire) and looking straight up to the top of the limestone cliffs that surround them. I wonder whether this jagged shape made by the edges of the clifftops gave the Scar its name - can't find anything on the internet that verifies or contradicts this though.

Camera/lens settings: ISO 100, f/9, 1/400s, 18mm, hand held (overall exposure increased and sky darkened with brush in Lightroom)
