Protecting the landscape heritage of the fens

The fenland has always been a land of mystery. This is particularly true when trying to unravel the complex history of dynamic changes in the landscape, which are directly linked to both sea level and climate. Thanks to an increase in research in recent years, much...

The Geology of the Lower Cam and Wicken – From Horningsea to Upware in 10 Easy Steps 

 

By Dr Steve Boreham

This talk will describe the architecture of Holocene and earlier deposits in the Wicken Vision area, where the Lower Cam valley joins southern Fenland.  This area has two disparate sedimentary systems. The deposits are sometimes cryptic, and outcrops and topography are often mantled beneath an overgrowth of late Holocene peat. The Wicken Vision is a hundred-year scheme by the National Trust to create a new 53 km2 nature reserve between Cambridge and Wicken Fen. The area is characterised by its flat, low-lying topography and by soils developed on Holocene peat overlying clay-rich bedrock. However, such a simplistic description masks a wealth of geological complexity.

Dr Steve Boreham was formerly a researcher at University of Cambridge specialising in the Pleistocene and later sedimentation events in the wider Cambridgeshire area. In 2015 he created WildReach to provide information about Wildlife Resources around the village of Reach, Cambridgeshire.

Field Trip Report – Burwell Local Geological Sites

The society organises occasional field trips to view important geological sites within the county and hopefully further afield in post pandemic times. These trips are primarily for our members.

In early summer 2021 we had a popular visit to the Burwell Local Geological Sites and are scheduling some others to East Pit, Cherry Hinton, a walk along the Fen Edge from Swaffham Bulbeck to Reach, a visit to Nine Wells chalk spring and a tour of the building stones of Cambridge city center. These are primarily for the benefit of members: any member wishing to participate should contact us.

A write up for this trip may be found here.
