Rook Wood ridge is an arcuate ridge that stands in isolation, superimposed on the underlying land. It is glacial in origin, but its origin and the processes which formed it are still debated and due to its enigmatic status it is a very important feature. The arcuate form and the steep slope visible in this photo would suggest it is an end-moraine type of feature with the steep slope being an ice contact slope (where the photograph is taken from would have been under the ice of a glacial lobe). However, it is composed of very mixed sediment of sand, gravel and rounded cobbles which is distinctly stratified with cross-stratification suggesting formation by flowing melt water.
