On 7th November Sue Beasley, a Bonby resident, gave us a very interesting archaeological talk “Valley of Whispers” about Bonby and surrounding areas. During the last ice age, a glacier extended across this area almost to where Doncaster now is. The main glacial front was at Escrick where the Escrick moraine marks its furthest extension. This was the northern limit of an extensive lake which was impounded by the blocking of the Humber Gap by another ice front. The lake bottom gradually filled with clay sediments which are up to 20 metres thick in some places. The clay sediments are locally overlain by peat deposits forming raised mires. At the base of the peat layers are the remains of a buried forest.
