Hastingford Cutting is a 0.05 hectare (0.12 acre) geological Site of Special Scientific Interest in East Sussex, England. The site was notified in 1990 under the Wildlife and Countryside Act 1981.
A laneside exposure of the Hastings Beds Group here shows 5 m of the top Ashdown Sand Formation and 0.75 m of the basal Wadhurst Clay Formation. The site is important for showing a different fluviatile facies in the top Ashdown beds from that at Brede (31 km east south east).
Coarse sandstone with siliceous pebbles and fossil charcoal fragments fill a channel, which is interpreted as part of a braided river system feeding sediment into the Weald Basin. The whole is overstepped by the Top Ashdown Pebble Bed horizon followed by the sandstones and clays of the Wadhurst Clay Formation interpreted as a lake/lagoon shoreface like the sequence at the Brede site.
