Evidence was found of a Shepherd Neolithic archaeological site in the area around the monument, on the south and west of the hill. The site was discovered and a collection of flint tools used during the Neolithic Revolution was made by Lorraine Copeland and Frank Skeels in 1965. Materials recovered included blade-butts with scraping edges or notches, borers, cores (one with a twin edge) and small flakes. Some pieces were vaguely bifacial. The flints found were in a grey or chocolate-brown colour with some having a shiny patina.
