The Quaternary history of the Avon Valley and Bristol district

Abstract

The sites described in this chapter were selected to document the glaciation and subsequent landscape development of the Bristol district and Avon Valley (Figure 10.1). This region contains important and unique evidence for a very early glaciation. Especially important are the glacial deposits of the Kenn Formation and associated landforms, distributed widely throughout the area, and the ?Stage 15 interglacial deposits of the Yew Tree Formation, which overlies the Kenn Formation of the Kenn lowlands. The Avon Valley contains a potentially important terrace sequence post-dating the glacial deposits, and important cold-stage aeolian and col-luvial sediments are preserved at Holly Lane, Clevedon.
