The cliffs of Alum Bay, showing the steeply-dipping multi-coloured sands above the white Chalk, with shallower dips towards the northern end.

The mountains are an important source of alunite, from which alum is extracted. The mineral was discovered there in 1461, and extensively mined until the mine closed in 1941, after almost 500 years; for much of this time it was the principal source of alum in Europe. The Tolfetano breed of horse originates in the area, and takes its name from it.
