Attborough Swallet

Caves of the Mendip Hills

Attborough Swallet (also known as Red Quar Swallet) is a cave in Chewton Mendip in Somerset, England. It is unusual for a cave on the Mendip Hills in that it is formed from Dolomitic Conglomerate and Marl rather than ordinary limestone. The main part of the cave was first entered in 1992, although Red Quar Swallet had been dug in the 1930s and the entrance shaft is now a concrete pipe.It takes its name from the Attborough field in which the entrance is situated. Red Quar Swallet comes from the small scale quarrying of red Triassic conglomerate.The underground stream feeding water into the sump flows into Wigmore Swallet.

Priddy Mineries
Priddy Mineries

Priddy Mineries (grid reference ST547515) is a nature reserve previously run by the Somerset Wildlife Trust. It is in the village of Priddy, on the Mendip Hills in Somerset. The reserve lies 3 miles north of Wells and 1.5 miles east of the village of Priddy. It is a site of 50 ha (123 acres) and is part of the Priddy Pools Site of Special Scientific Interest (SSSI). It is mostly grassland / heather mosaic with an area of valley mire and some nutrient-poor pools. The site is one of the beauty spots of Mendip partly due to these pools with the changing colours of the vegetation and the pines and the heather slopes. It is adjacent to Stock Hill woodland, and one of the paths form part of the long distance national footpath, the Monarch's Way. There are wide range of plant and small animal species. More than 20 species of dragonflies have been recorded, most of them breeding on site. In particular this is the only site in the Mendips for the Downy Emerald. There are numerous species of water bug including Water stick-insect (Ranatra linearis) and also all British species of amphibian, except for the Natterjack Toad, in good breeding numbers. The site was worked for lead for many centuries, probably 2000 years until 1908, and the earlier workings were obliterated by those of the Victorians which left a legacy of pools, mounds and spoil heaps. The buddle pits and condensation flues are the remains of the Waldegrave lead works of that time. The site is of great interest to industrial archaeologists and also to cavers on account of the existence of Waldegrave swallet (opened 1934) and the possible rediscovery of Five Buddles Sink or Thomas Bushell’s Swallet (named after the man who first discovered it).A barrow or Tumulus can be found in the northern part of the Reserve.

Wurt Pit and Devil's Punchbowl
Wurt Pit and Devil's Punchbowl

Wurt Pit and Devil's Punchbowl (grid reference ST543537) is a 0.2 hectare (0.5 acre) geological Site of Special Scientific Interest between East Harptree and the Priddy Circles in the Mendip Hills, Somerset, notified in 1987. Natural England describes the site as: "This site consists of the two largest subsidence depressions in the Mendips, formed by the underlying limestones having been dissolved by subterranean waters causing the surface rocks to collapse into the void. Clear evidence of their being collapsed structures rather than erosional or solutional features, is gained from the fact that the surface rocks at both localities are insoluble, being marls at Devil's Punchbowl and a series of limestones and clays which have been impregnated by silica at Wurt Pit." "The silica-enrichment of the limestones and clays at Wurt Pit (known as the 'Harptree Beds', of early Jurassic age) is also of considerable mineralogical importance since it took place as part of the main phase of mineralisation which emplaced the principal Mendip orefields during Jurassic times. The Harptree Beds show varying degrees of silica-enrichment, and also contain traces of other minerals, such as limonite and yellow ochre (hydrous ferric oxides), barite (barium sulphate), sphalerite (zinc sulphide) and galena (lead sulphide)." Wade and Wade, in their 1929 book Somerset, described the Devil's Punch Bowl as one of the most notable Swallet Holes on the Mendips
