Coombe Wood


Site of geological interest with potential to provide information about the underlying geology. Any significant excavations in the area should be recorded.


Site description

At the western edge of the Rayleigh Hills the A13 climbs the steep incline of Bread and Cheese Hill. On the left hand (north) side of the road the steeply sloping ground of Coombe Wood can be seen. Coombe Wood is a mostly native woodland situated on the Claygate Beds with Bagshot Sand on the highest ground. The layers of sandy clay that make up the Claygate Beds can be seen in the sides of a stream that cuts through the wood in a very steep valley which is almost a ravine. The underlying geology is also revealed by rabbit burrows and the rootplates of fallen trees.

A couple of hundred metres north of the wood is St. Peter's Church (TQ 782 887) which has a similarly steeply-sloping churchyard and a fine view to the west. This is a good place to appreciate the remarkable amount of erosion that has taken place over the last few hundred thousand years as the Thames and its tributaries have carved the modern valley leaving remnants of high ground here and also further west at the Langdon Hills.
