This site exposed a former channel of the River Thames during an interglacial period around 575,000 years ago, probably where it met the early River Medway. The site was found in 1939, but not excavated until the 1980s. Many fossils were found, including rhinoceros and giant deer, many freshwater shells and an extensive pollen record, allowing geologists to reconstruct the fauna and flora of the time.[4]
As the site has been filled in, no geology is visible.[4]
