Just found old photo of Silbury Hill (A guide to Prehistoric England -Nicholas Thomas 1960), which answers a question that has been worrying me all week. Q; how do you know what the top of S/h looks like after all that excavation? This photo shows a snow clad Silbury Hill with a slightly domed top, all the tops on the photos show flat platforms. Technically illiterate about putting photos from books on site!!
