Upper Common Pits is a 3-hectare (7.4-acre) geological Site of Special Scientific Interest in the north of Gomshall in Surrey.

[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.
