NORTH YORKSHIRE, ENGLAND—A Mesolithic camp site, consisting of a small structure and flint tools dating to between 6000 and 8000 B.C., has been discovered alongside the A1, which stretches 410 miles from London to Edinburgh. “This was a place that people knew of—a place they could return to on many occasions to stay overnight during their travels. There is evidence of people using the route and moving through the area over periods of time,” archaeologist Steve Sherlock told The Express. The site was found while excavating a Roman road that also runs along the A1, and the Roman shops and baths of the town of Cataractonium.
