Ham Green SSSI
Encyclopedia
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.
A number of Acheulian handaxes have been found in the area.
