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.
The Upper Greensand to Grey Chalk transition has a unique and very fossil-rich 'Popple Bed' well exposed above the Chert Beds. A diverse assemblage of bivalves, gastropods, ammonites, brachiopods and echinoids can be found, mainly phosphatised casts. It is a key locality for lowermost Cenomanian palaeontology.
Dead Maid quarry industrial estate is just to the west of Mere north of the B3095/3092 almost opposite the turn-off to Gillingham. Turn into the Trading Estate and follow round to the left and then right - behind the buildings there is lots of parking at the back of the trading estate just next to the quarry face. It is an S.S.S.I. for the only clear location showing the junction between Upper Greensand and the Lower Chalk. The whole face is obscured by ivy, grass and brambles. Bring gardening gloves, secateurs, loppers hard hat and maybe eye defenders to keep out the debris. Bringing a packed lunch is recommended.
In the afternoon, when the work is finished, there will be a short guided walk by Isobel Geddes up to Mere Castle Hill and Long Hill to view the local geology from above, looking at local building stones on the way up. This will last no more than an hour.
