Late in 2004 an exciting discovery was made by HWTMA divers inspecting the site. A pit containing worked flints was lying within the ancient land surface. Additional material at the site included a worked flint embedded in a sapling exposed on the cliff face. The feature was located 2 metres to the west of the hearth and 30cm below the Mesolithic submerged forest. Adjacent to the timbers burnt and worked flint was exposed in the cliff face. The site predated the inundation that formed the landscape.
Support from SCOPAC and BAE Systems enabled HWTMA divers to visit the site on several occasions in 2004. Samples were collected in monolith tins which were assessed for pollen and environmental evidence, and a branch from the archaeological horizon beneath the Mesolithic forest level was sent for C14 (radiocarbon) dating.
On-going inspection by divers during the summer of 2004 showed this area to be rapidly eroding. The excavated pit site was protected with sand bags, but this could only be a temporary measure. The confirmation of this rapid erosion demonstrated that there was a need for urgent action to recover what remains of this unique discovery, before the information contained in this non-renewable resource is lost forever.
