Brief description of site:

Former brickpit now containing an industrial estate. Wall of former pit still visible with exposure of boulder clay (glacial till) and potentially also Kesgrave (Thames) Gravels.


Summary of geological interest

Stansted Distribution Centre Business Park at Start Hill is mostly located on the site of the former Tilekiln Green Brick Pit, which dates back to the nineteenth century. In 1945 the walls of the pit were recorded as exposing Kesgrave (Thames) Sands and Gravels, overlain by boulder clay (glacial till), with London Clay at the base.

A high, vertical section still exists at the rear of the Mercedes Benz Truck Centre car park with chalky boulder clay visible and the possibility of Thames gravel and London Clay under the talus. With the permission of the land owner, vegetation and talus clearance could be undertaken.

Access would be available either from the Flitch Way or from the adjacent Scania car park (with the permission of the landowner).
