At North Woolwich archaeologists found evidence for evidence for a seasonal encampment in the lower Thames floodplain, dating to the later Mesolithic (c. 8,500 to 6,000 years ago). The site was located on what would have been an area of sandy, higher ground close to the river.
Two scatters of struck flint were found, along with burnt flint and traces of hearths. The larger flint scatter indicates that someone had partly made a flint tool there, probably an axe or adze, leaving a scatter of flint waste.
The activity can be dated by the presence of a small number of identifiable pieces, such as two microliths. This site is a rare survival. By their nature sites from this period are ephemeral – temporary campsites or toolmaking sites, such as this one, that were not in use for long. The material that is left behind, such as flint scatters or the traces of campfires, often does not survive.
