West Wood

Site of geological interest with disused pits that have provided information about the underlying geology. Any further significant excavations in the area should be recorded.


Site description

West Wood has a varied geology which has influenced the species of trees that exist from valley floor to hill top. The Prittle Brook flows in the valley in the centre of the wood, which is underlain by a bedrock of Claygate Beds. To the north and south the rising ground gives way to the overlying Bagshot Sands.

On the highest ground, to the north and south, there are overgrown shallow pits where ‘exotic’ gravel can be found. This is Daws Heath Gravel, which outcrops on each side of the valley just beyond the north and south boundaries of the wood but has migrated here during the coldest periods of the Ice Age by the process of ‘solifluction’ where saturated ground moves downhill under gravity. Daws Heath Gravel is an ancient remnant of a terrace of river gravel deposited by the River Medway when it flowed across eastern Essex in the early part of the Ice Age, perhaps as much as a million years ago, and contains unusual rock types, including some from the Weald of Kent (see also Pound Wood Nature Reserve in Daws Heath).
