Geology at Greenham Common

Leader: Lesley Dunlop

Meet at the Control Centre car park, RG19 8BZ, accessed from a roundabout on Bury’s Bank Road, for a walk of about 1.5 miles. We will start on the plateau of Greenham Common and include part of Bowdown Woods. Greenham and Crookham Commons lie on a ridge between the rivers Enborne and Kennet. The ridge consists of Eocene deposits of acid, sandy clays, overlain by plateau gravels and seated on impermeable clay.
