This is a Geological Conservation Review site. The site shows a section through red-brown, gritty, stony silts, with abundant Greensand chert Pleistocene sediments. These deposits appear to be heavily-cryoturbated terrace gravels of presumed fluvial origin, although a fluvio-glacial origin has also been suggested.[1] A number of Acheulian handaxes have been found in the area.
