Upminster interglacial sites (general), UPMINSTER, London Borough of Havering, General information
William Whitaker, in his book The Geology of London and Part of the Thames Valley (1989) reported that bones and shells in sand were found when digging a well at Cranham Hall (TQ 571 861). Whitaker states that they were found at a depth of 30 feet and “as many as 20 buckets full might have been collected of the shells”.
Also in Upminster, a temporary sewer excavation in April 1992 at the junction of South View Drive and Acacia Drive (TQ 553 861) yielded shells typical of an Ice Age interglacial deposit.
Both of these sites appear to have revealed interglacial sediments associated with the 300,000 year old Lynch Hill/Corbets Tey terrace of the Thames. It is possible that they are the same age as the interglacial deposits found at Park Farm Road, Corbets Tey (see separate site record) but further research is needed to establish a link between them.
