Excavations by M Cook and A Johnson of the Wey & Arun Canal Trust took place to the west of the east parapet wall of Gosden aqueduct. The single trench revealed the counterfort design of the parapet wall, the clay puddling layer that formed the original canal channel lining and remains of the tow path. The shallow depth of the puddling, relative to the parapet wall, indicates that the wall was lowered after the canal went out of use. No removal of deposits associated with the canal construction appeared to have taken place although some degree of truncation is likely. The clay puddle lining was strangely deformed to its west possibly by the passing and re-passing of heavy vehicles after the aqueduct became a thoroughfare. (Bulletin 443)
