This preceded the severe Anglian ice age, which is also seen, marking the transition to glacial conditions. The site is described by Natural England as "of prime importance for the correlation between Pleistocene stratigraphic sites in the Thames and East Anglian areas".[1] Ice wedge polygons just below the Anglian layer reveal very cold conditions just before the advance of the ice sheet across East Anglia.[4] The site has now been filled in and is part of a field.
