Geology and Natural History
The downland is part of the Southern England Chalk Formation which runs from Dorset in the west to Kent in the east and also includes the Dorset Downs, Purbeck Hills, Cranborne Chase, Wiltshire Downs, Salisbury Plain, the Isle of Wight, Chiltern Hills and the North and South Downs.
The area is a site of scientific interest in numerous fields and has an internationally important habitat for early gentian. Geologically, its chalk downs, dry valleys and sarsen outcrops are of note, the last in the area around Marlborough providing material for many of the Neolithic and Bronze Age sites in the area such as Avebury Henge.

“Profundity easily turns into dullness and astuteness deteriorates into wit. Be guided by natural common sense and it will accommodate great and small.”
—Franz Grillparzer (1791–1872)
