Wansunt Pit

Wansunt Pit is a 1.9-hectare (4.7-acre) geological Site of Special Scientific Interest in Dartford Heath between Crayford in the London Borough of Bexley and Dartford in Kent. It is also a Geological Conservation Review site. It is important geologically because it exposes the Dartford Heath Gravel, and the relationship of this exposure to the Swanscombe sequence and the Thames Terraces is a controversial issue in Thames Pleistocene studies. The site is part of Braeburn Park, a nature reserve managed by the London Wildlife Trust.
