Recent excavations at the Valdoe Quarry in West Sussex have provided a new locality for the study of human activity and environment in the Middle Pleistocene. Fieldwork and analysis, funded through the Aggregates Levy Sustainability Fund, were undertaken at the Valdoe Quarry ahead of a renewed and final stage of gravel extraction at the site. Through geological mapping, sedimentary sequences entirely comparable to those at the Boxgrove Quarry, 6 km to the east, were sampled in order to determine their archaeological potential and characterize the associated paleoenvironmental conditions. This paper provides an introduction to this work ahead of detailed publication of the results. Initial results suggest that the site represents a locality within the same contemporary recessional paleolandscape as the main Boxgrove site.
