The site is thought to be the remains of a kettle hole, a pond formed in the void remaining after a submerged glacial calf block melted. In contemporary times Campfield Kettle Hole is a mix of bog and pond.[1][2] Location and natural featuresCampfield Kettle Hole is situated in the north-east of England, immediately south of the Anglo-Scottish border in the county of Northumberland, some {{convert|0.7|mi}} south of the town of Cornhill-on-Tweed. The pond lies at {{convert|31|m}} above sea level within mildly undulating terrain, and is some {{convert|0.09|mi}} north-south and {{convert|0.22|mi}} east-west. The western end is a permanent pond; the eastern-end is prone to occasional flooding; the remainder of the pond has become peat-filled.[1][2] The local area has a number of other kettle hole ponds; a second, Barelees Pond, lies {{convert|0.65|mi}} east of Campfield.[1][2] VegetationThe kettle hole has deep waterlogged peat soils supporting a carr woodland of birch (Betula sp.) with Scot’s pine (Pinus sylvestris). The woodland floor has bog-mosses (Sphagnum spp.), and hare’s-tail cotton grass (Eriophorum vaginatum) with purple moor-grass (Molinia caerulea) and wavy hair-grass (Deschampsia flexuosa).[2] The western end of the pond is fringed with yellow iris (Iris pseudacorus), water plantain (Alisma plantago-aquatica) and willow (Salix spp). The perimeter has yellow iris and reed canary-grass (Phalaris arundinacea). The uncommon beetle Agabus uliginosus dispar has been recorded from the wetter areas of the site.[2] The condition of Campfield Kettle Hole was judged to be unfavourable-recovering in 2013, with previous concerns about tree encroachment settled.[3] See also
