Evaluation by G Hayman of SCAU for Balfour Beatty Civil Engineering Ltd of land to be used as a tip site for soil disposal from the M25 Junction 8-10 widening. Several pieces of struck flint probably of Neolithic or Bronze Age origin were recovered from the ploughsoil. No evidence for a feature noted on aerial photographs was discovered and it seems certain that the crop mark was caused by differential ploughing.
