Summary of geological interest

Sarsens are boulders of extremely hard sandstone that were formed about 55 million years ago during the Palaeocene period in sandy strata called the Reading Beds that occur on top of the Chalk.

Most sarsen stones in Essex were carried here by the Anglian ice sheet which covered most of Britain during the coldest period of the Ice Age, some 450,000 years ago. Sarsens are usually found in North Essex and Suffolk and it is unusual to find one this far east. It is possible that this stone was carried here from the North Downs of Kent by the River Medway.
