Bleadon Hill (grid reference ST351574) is a 13.52 hectare geological Site of Special Scientific Interest just north of the village of Bleadon, North Somerset, notified in 1999.
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.[1]
There is evidence or agricultural use of the land in the medieval period and possibly from Roman times.[2]
