Ham Green SSSI () is a 1.1 hectare geological Site of Special Scientific Interest near the village of Ham Green, North Somerset, notified in 1990. 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.〔(English Nature citation sheet for the site ) (accessed 9 January 2008)〕 A number of Acheulian handaxes have been found in the area. ==References==
