A photographic composite panorama, assembled from oblique aerial photographs commissioned by Mr D. E. Maynard of the Port of London Authority and taken by Commission Air in The remains of earlier landslides in the foreshore, highlighted by boundary shears on outcrops and septarian nodules, is evidence of the penetration of the basal slip surface into the London Clay beneath the shore platform level.
