A walk to view London geological history.

Hadleigh, Essex, ERMS Trail, Essex 

Limited to 30 Places

The rock layers seen in Hadleigh Park tell a story of tropical seas, swamps and deltas over 50 million years ago; and of course within the last two million years the ice ages have contributed to the scenery we see today.

Look out for some of the best views in Essex, erosion in action, spring lines and of course a Norman castle, painted by John Constable.

The classic ERMS visit. Not to be missed if you love Ice age geology and finding puddingstones, sarcens and all kinds of exotic specimens in the gravel reject pile. There are also occasional fossils found such as flint echinoids and sponges

To be confirmed

Limited to 30 Places

Essex’s premier geological site where one can find the only cliffs in Essex. These yield London clay and Red Crag fossils and display rotational landslips. Further along the beach ancient land surfaces are visible and find occasional stone tools on the foreshore. The site was used by the military in WWII and there are also remains of this to be seen on the cliff tops, and occasional bullets (spent) and shrapnel to be found on the beach.

Norwich Castle museum and a side visit to the stored Mammoth remains.


Stored in an impressive Norman keep, the museum collection spans every period of East Anglian history with a fascinating geological section. This includes the cast of a sea urchins internal structure and a woolly mammoth stored offsite which we hope to view. There are also some spectacular glass models of delicate creatures such as jelly fish, and an impressive array of Celtic and Anglo Saxon artefacts.
