Ash Fell Edge

Ash Fell Edge is a Site of Special Scientific Interest in Cumbria, England. It is located within the Yorkshire Dales National Park 1.5km northeast of the village of Ravenstonedale. This area is protected because of the Carboniferous limestone geology here and the fossils preserved in the sediments. The rocks here formed on the floor of a shallow sea about 345 million years ago.
