Upper Common Pits is a 3-hectare (7.4-acre) geological Site of Special Scientific Interest in the north of GomshallinSurrey.[1][2] It is a Geological Conservation Review site.[3]
These pits have yielded deposits which are part of the Netley Heath Beds, which date to the Early Pleistocene and are related to the Red Crag Formation. There is a considerable difference in elevation compared with the Red Crag of East Anglia, suggesting differential warping. Near the base there are sandy deposits with many marine fossils.[4]
The site is private land with no public access.
