1980 but which cutting?

This photo is one of mine but I can't figure out which cutting it is. I may just be getting the perspective wrong as I try and work it out but I can't match it up with this one of the same season of Bernie Dawson's. Update: illumination from Phil: Cutting  is P5, O6 and P6, at the end of the Long Mound at the intersection with the 1D bank, showing the first traces of the last Neolithic entrance from the NW, looking across the fence into the National Trust area, where the hollows and bumps are the 18th century quarries. The Long Mound is just off to the right.
