Survival expert Ray Mears has been taking some tips from a Sussex archaeologist.
Dr Richard Carter, a geology lecturer at the University of Sussex, picked out a location for the television star to film part of his new BBC2 series Wild Food.
The show needed a suitable site to recreate conditions hunter-gatherers would have experienced in the Stone Age and turned to Dr Carter, an expert in Sussex geology, for help.
He pointed them in the direction of Chiddinglye Wood Rocks, near his Ardingly home, a designated site of scientific interest dated to the Mesolithic period between 10,000 and 6,000 years ago.
Dr Carter said: "It is considered highly significant in terms of archaeological interest. It has been well preserved. There is no sign of human interference and little erosion"
He spent a day on set with Mears and co-presenter Professor Gordon Hillman, an old friend, advising them on the archaeological evidence and activities which would have taken place at the rocks.
