Wansunt Pit is a {{convert|1.9|hectare|acre|adj=on}} 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.{{Cite web |url=http://www.sssi.naturalengland.org.uk/citation/citation_photo/1003328.pdf |title=Natural England, Wansunt Pit SSSI citation |access-date=11 July 2012 |archive-date=24 October 2012 |archive-url=https://web.archive.org/web/20121024053555/http://www.sssi.naturalengland.org.uk/citation/citation_photo/1003328.pdf |url-status=dead }}{{cite web | url=http://jncc.defra.gov.uk/default.aspx?page=4174&gcr=846 | title=Wansunt Pit, Dartford Heath (Quaternary of the Thames) | publisher=Joint Nature Conservation Committee | access-date=16 January 2016}} The site is part of Braeburn Park,{{cite web|url=http://www.bexley.gov.uk/CHttpHandler.ashx?id=13119&p=0|title=SINC Review|author=London Wildlife Trust|publisher=London Borough of Bexley|page=116|access-date=18 January 2016|archive-date=25 January 2016|archive-url=https://web.archive.org/web/20160125234350/http://www.bexley.gov.uk/CHttpHandler.ashx?id=13119&p=0|url-status=dead}} a nature reserve managed by the London Wildlife Trust.{{cite web|url=http://www.wildlondon.org.uk/reserves/braeburn-park |title=Braeburn Park |publisher=London Wildlife Trust|access-date= 16 January 2016}}
