"One of my old Physics teachers was an expert on Stone Henge. Did a lot of original research in the 1980s."
Did your teacher publish anything? I'm aware of Alexander and Archie Thom [1], John North [2] and Fred Hoyle [3] as well as the pop science books by Gerald Hawkins.
PS: remember that climate in Britain was very different from now and changed a lot during the construction of megalithic sites. Inland Britain was as you say covered with dense forest so river valleys and coastal areas were very important then.
