Wiltshire's landscape is inextricably bound up with the rocks beneath the surface. It is our aim to raise public awareness of Earth Sciences and draw peoples attention to the way the landscape, and the towns and villages within it, are influenced by the underlying geology.


Geological site clean-up at Bradford-on-Avon   


Saturday 25th November at 10am. 


 The site is located at the north end of the British Waterways car park at the end of Baileys Barn, off Moulton Drive (BA15 1BX).  It is behind the information board by the picnic tables above the Kennet & Avon canal (southeast of the lock and marina on Frome Road). 

Grid. Ref. ST 826 601 


In 2007 the group put up an information/interpretation board near the canal in Bradford on Avon and excavated a small area to reveal the geology, to show how the area would have looked 165 million years ago. The site is on the dip-slope of the Cotswold Hills, in the mid-Jurassic Forest Marble Formation. This rock formation, some 24 metres thick, consists of alternating limestones and clays. A particularly thick layer of clay, know as the Bradford Clay, occurs here above a Jurassic limestone sea-floor.  A number of fossils, including sea lilies and brachiopods, can be found.


The site has been monitored and maintenance carried out since 2007 however it has now reached the point where it needs clearing once again. The clay walls of the pit have become quite overgrown and the clay has washed down into the hollows in the limestone floor.


If you want to help, please bring gloves, a trowel, spade, mattock, clippers/pruning shears, a pruning saw (just in case), garden fork, maybe a pickaxe to lever tough roots out and rugs to move waste soil. If you don't have all this equipment, there will be a selection on site for people to use.


If you have any queries concerning the event, please e-mail isobelgeddes@talk21.com
