Stanage south end 2

The southern end of Stanage Edge, the longest of the Eastern Edges, in the Peak District National Park, Derbyshire.

Stanage Edge is comprised of Rivelin Grit (aka Chatsworth Grit), Namurian age, Upper Carboniferous. The coarse-grained gritstone was deposited in a series of delta distributary channels. The gritstone is normally strongly cross-bedded, and intraformational erosion surfaces are common.

The Edge has been worked for millstones in several places and examples such as these can be found in many places, lying where they were abandoned when the demand for imported French stones rose in the latter part of the 19th century.
