The site is a Geological Conservation Review site, as it shows a low ridge of calcite-cemented Pleistocene sand and gravel on its southern side. Various marine or glacial origins have been postulated for the sediments and it has even been suggested that this is a Mesozoic beach conglomerate. On the basis of the sedimentology, it is most likely that these sediments accumulated during the Quaternary when an ice sheet rested against Bleadon Hill.
