Sunday 24th July Chafford and Purfleet
A visit to walk two proposed geological trails, prior to production of trail guides. The trails will cover the remarkable evidence of former routes of the Thames during the Ice Age and the early humans that lived here. This part of Essex has geological sites of this age that are internationally important and the trail will visit several of them. We will also visit the submerged forest on the Thames foreshore at Purfleet.
