  • Palaeolithic and Pleistocene Sites of the Mendip, Bath and Bristol Areas
    Proc. Univ. Bristol Spelacol. Soc, 19SlJ, 18(3), 367-389 PALAEOLITHIC AND PLEISTOCENE SITES OF THE MENDIP, BATH AND BRISTOL AREAS RECENT BIBLIOGRAPHY by R. W. MANSFIELD and D. T. DONOVAN Lists of references lo works on the Palaeolithic and Pleistocene of the area were published in these Proceedings in 1954 (vol. 7, no. 1) and 1964 (vol. 10, no. 2). In 1977 (vol. 14, no. 3) these were reprinted, being then out of print, by Hawkins and Tratman who added a list ai' about sixty papers which had come out between 1964 and 1977. The present contribution is an attempt to bring the earlier lists up to date. The 1954 list was intended to include all work before that date, but was very incomplete, as evidenced by the number of older works cited in the later lists, including the present one. In particular, newspaper reports had not been previously included, but are useful for sites such as the Milton Hill (near Wells) bone Fissure, as are a number of references in serials such as the annual reports of the British Association and of the Wells Natural History and Archaeological Society, which are also now noted for the first time. The largest number of new references has been generated by Gough's Cave, Cheddar, which has produced important new material as well as new studies of finds from the older excavations. The original lists covered an area from what is now the northern limit of the County of Avon lo the southern slopes of the Mendips. Hawkins and Tratman extended that area to include the Quaternary Burtle Beds which lie in the Somerset Levels to the south of the Mendips, and these are also included in the present list.

  • Mells River Sink — a Spelaeological Curiosity in East Mendip, Somerset
    93 Proc. Univ. Bristol Spelaeol. Soc, 1982, 16 (2), 93-104. MELLS RIVER SINK — A SPELAEOLOGICAL CURIOSITY IN EAST MENDIP, SOMERSET by W. I. STANTON ABSTRACT The site is a cleft in the side of the Mells River that acts as a resurgence in winter and a swallet in summer. An excavation, 1974-78, began 21m above, and ended 2m below, river level. It showed (hat a high-leve! resurgence was active in the Middle Devensian, and was buried under later deposits. Scattered finds of archaeological significance included Woolly Rhinoceros bones and a First Century bronze brooch. Water tracing experiments proved that the Sink is the upper end of an active underground oxbow to the Mells River, 2.5 km long. The cleft was developed along a neptunian dyke of Lower Lias age. Bubbling springs and 'cave, coral" are briefly discussed. INTRODUCTION The Mells River rises at Gurney Slade and flows east below the north flank of the Mendips to join the River Frome at Frome. It receives water from the Carboniferous Limestone resurgences of Winter Well, Gurney Slade, Ashwick Grove, St. Dunstan's Well, Whitehole, Cobby Wood, Hapsford and other smaller springs (Barrington and Stanton, 1977). Some of these resurgences fail in dry weather, and one of them, Mells River Sink, is so close to the river bed that, at times, the spring flow actually reverses and part of the river disappears down the hole. In the drought summer of 1976 about one quarter of the Mells River was lost into Mells River Sink. At the village of Mells the Mells River leaves undulating low ground to enter a wooded gorge (Wadbury Valley) incised by super imposed drainage into the north flank of East Mendip (Barrington and Stanton, 1977, p 220).

  • Somerset Geology-A Good Rock Guide
    SOMERSET GEOLOGY-A GOOD ROCK GUIDE Hugh Prudden The great unconformity figured by De la Beche WELCOME TO SOMERSET Welcome to green fields, wild flower meadows, farm cider, Cheddar cheese, picturesque villages, wild moorland, peat moors, a spectacular coastline, quiet country lanes…… To which we can add a wealth of geological features. The gorge and caves at Cheddar are well-known. Further east near Frome there are Silurian volcanics, Carboniferous Limestone outcrops, Variscan thrust tectonics, Permo-Triassic conglomerates, sediment-filled fissures, a classic unconformity, Jurassic clays and limestones, Cretaceous Greensand and Chalk topped with Tertiary remnants including sarsen stones-a veritable geological park! Elsewhere in Mendip are reminders of coal and lead mining both in the field and museums. Today the Mendips are a major source of aggregates. The Mesozoic formations curve in an arc through southwest and southeast Somerset creating vales and escarpments that define the landscape and clearly have influenced the patterns of soils, land use and settlement as at Porlock. The church building stones mark the outcrops. Wilder country can be found in the Quantocks, Brendon Hills and Exmoor which are underlain by rocks of Devonian age and within which lie sunken blocks (half-grabens) containing Permo-Triassic sediments. The coastline contains exposures of Devonian sediments and tectonics west of Minehead adjoining the classic exposures of Mesozoic sediments and structural features which extend eastward to the Parrett estuary. The predominance of wave energy from the west and the large tidal range of the Bristol Channel has resulted in rapid cliff erosion and longshore drift to the east where there is a full suite of accretionary landforms: sandy beaches, storm ridges, salt marsh, and sand dunes popular with summer visitors.

  • Glastonbury Companion
    John Cowper Powys’s A Glastonbury Romance: A Reader’s Companion Updated and Expanded Edition W. J. Keith December 2010 . “Reader’s Companions” by Prof. W.J. Keith to other Powys works are available at: http://www.powys-lannion.net/Powys/Keith/Companions.htm Preface The aim of this list is to provide background information that will enrich a reading of Powys’s novel/ romance. It glosses biblical, literary and other allusions, identifies quotations, explains geographical and historical references, and offers any commentary that may throw light on the more complex aspects of the text. Biblical citations are from the Authorized (King James) Version. (When any quotation is involved, the passage is listed under the first word even if it is “a” or “the”.) References are to the first edition of A Glastonbury Romance, but I follow G. Wilson Knight’s admirable example in including the equivalent page-numbers of the 1955 Macdonald edition (which are also those of the 1975 Picador edition), here in square brackets. Cuts were made in the latter edition, mainly in the “Wookey Hole” chapter as a result of the libel action of 1934. References to JCP’s works published in his lifetime are not listed in “Works Cited” but are also to first editions (see the Powys Society’s Checklist) or to reprints reproducing the original pagination, with the following exceptions: Wolf Solent (London: Macdonald, 1961), Weymouth Sands (London: Macdonald, 1963), Maiden Castle (ed. Ian Hughes. Cardiff: University of Wales Press, 1990), Psychoanalysis and Morality (London: Village Press, 1975), The Owl, the Duck and – Miss Rowe! Miss Rowe!

It was most successful. The accommodation and main centre were typical 1960s college space and served us well even INDUSTRIAL though the lecture room struggled to accommodate the numbers. The village was a delight – the ARCHAEOLOGY gardens of Cannington Court (now part of the college) were open to us and there were no less than five pubs to explore. The Conference Dinner was outside the capacity of the College so to Taunton Race NEWS 191 Course we went (regrettably not on a race night) and were served an excellent meal and at which the Winter 2019 AIA prizes were handed out (see page 19). The organization was faultless, well planned and well executed by members of the Somerset Industrial Archaeological Society led by Peter Daniel and Steve Miles. Steve established a precedent by Honorary President Prof Marilyn Palmer MBE bringing along his tribe in support – and support they did. Peter was also responsible for editing and leading the team that produced a revised version of the Somerset Gazetteer.

  • Mendip Woodland Habitat Action Plan
    MENDIP WOODLAND HABITAT ACTION PLAN Action plan name Mendip Woodland Background and vision Some parts of the Mendip District were identified as priority areas (Strategic Nature Areas or SNAs) for creating new native broadleaved woodland during a process called ‘Rebuilding Biodiversity’ or ‘Nature Map’. SNAs link areas of existing mapped areas of habitat identified as priorities in the UK BAP and identify priority areas for linking and buffering existing habitat patches with new habitat. The new South West Regional Spatial Strategy contains a map of SNAs for a variety of target habitats. (http://www.swenvo.org.uk/nature_map/downloads.asp - checked 05/02/2008). Woodland is a Rebuilding Biodiversity target for the following Natural Areas in Mendip District: the Mendip Hills, Thames and Avon Vales, the Wessex Vales and the Mid Somerset Hills (http://www.english- nature.org.uk/pubs/gis/tech_na.htm - checked 05/02/2008) The ultimate aim, by 2030, is for woodland SNAs to contain 30% of the target habitat and 30% other semi-natural Habitats. 1 Creation of such blocks of target and other semi-natural habitats is aimed at reducing gradual extinction of species from small patches of habitat and to allow species to adapt to climate change. In Mendip District, Strategic Nature Areas for woodland often overlap with Strategic Nature Areas for other target areas. Where this is the case, the target habitat for one SNA can form the other semi-natural habitat target for overlapping SNAs. Target habitats for SNAs that overlap with Woodland SNAs in Mendip District include: Calcareous Grassland (Hills in Mendip District and Mid Somerset Hills Natural Areas) Lowland Heathland, (Hills in Mendip District Natural Area) Neutral Grassland (Hills in Mendip District and Wessex Vales Natural Areas) Purple Moor Grass and Rush Pasture (Wessex Vales Natural Area) Plan species and habitats Additionally, to achieve Rebuilding Biodiversity targets there will be a need to create other semi-natural habitat alongside woodland.
