comprises a series of limestones, the thickest being the Great Scar Limestone which
outcrops prominently in Wharfedale and Littondale. Its name derives from the manner in
which it weathers and erodes into terraces along bedding planes. Being well jointed,
backwards retreat occurs by the successive fall of cube-shaped masses, thus retaining a
vertical bare rock face, or 'scar'. The Great Scar Limestone has been well studied, not
least because of the striking variety of
karst
features which it gives rise to,
