A Lidar survey was made as part of the Stiperstones and Corndon Hill Partnership. You can still see the fascinating interactive image, which shows the detail of the hill fort earthworks and other topological features at the following link:
In terms of archaeological information about the hillforts on Pontesford Hill, the main sources are Philip Barker’s report on his rescue excavation when they put the forestry road in in the 1960s. The reference for this is: –
Barker, P.A. 1972. An Emergency Excavation at Pontesford Hill Camp 1963. In F. Lynch and C. Burgess (eds.) Prehistoric Man in Wales and the West. Bath. Adams and Dart. pp. 345-353.
There’s also a paper by James Forde-Johnston in which he identifies the potential pairing of Lower Camp with Earl’s Hill hillfort and sets out his theory that the former acted as an ‘outpost’ for the latter for defensive purposes. However, I think most archaeologists would now question this.
Forde-Johnston, J. (1962) Earl’s Hill, Pontesbury and related hillforts in England and Wales. Archaeological Journal 119: 66-91.
