Archaeological monitoring and excavation was carried out at Birch Pit in 2012. The archaeological monitoring covered topsoil-stripping of an extraction area associated with the Stage 5 western extension of the quarry and was undertaken adjacent to areas excavated in 2007 and 2008.<1> Only two features were recorded - a post-hole containing pottery dated to the Late Bronze Age or early Iron Age and a ditch dating to the post-medieval or modern period. The majority of the stripped area was disturbed by activity associated with the construction and subsequent removal of a World War II airbase.
