Lauren Gibson’s artistic rendering of our interpretation of the Horse Butchery Site and the Boxgrove people. It shows how the site was situated in front of towering chalk cliffs on the edge of an intertidal lagoon. The cliffs to the north provided all the flint used in tool making at the site and, within a few hours, the tide would have begun to cover the site in fine silt, preserving evidence of the day’s activity.
