So, given the lack of evidence to support erection of the stones during the period defined by the radioactive determinations, is it possible that the site already existed and the few samples collected were the result of maintenance? If we can credit the Neolithic locals with building Stonehenge it’s even easier to believe them capable of looking after it, more so if it held as much mystery then as it does now. When the Ditch filled with silt following weeks of rain they cleared it with the only tools they had. According to Stonehenge in its Landscape (19:68) “Deposits of chalky mud are not uncommon on the bases of chalk-cut ditches, and appear to be the product of the first winter’s weathering”, and in the very next paragraph, “In one or two instances it is arguable that there has been some recutting of the Ditch fill as there is much less primary filling than is usual”. The origin of the fill becomes ever more doubtful in the pages that follow with the author suggesting “an anthropogenic element” in the deposition of some soil layers, another way of saying there had been human intervention.
