The Sandford Gulf and Other Lost Caves of Sandford Hill
THE SANDFORD GULF AND OTHER LOST CAVES OF SANDFORD HILL By R. M. Taviner During the 18 th century, miners’ working on the western outliers of the Mendip Hills intercepted several small but notable cave systems, including the Banwell caves, Loxton Cavern and Hutton Cavern. Most were subsequently lost, although several have recently been rediscovered by cave explorers, often by following clues provided by the antiquarians who dutifully recorded them. Not all of these caverns have been rediscovered however, including three well documented sites on Sandford Hill. The first, Elephant Cave - which contained the skeleton of a full sized elephant - was recorded in 1770, while the better documented Sandford Bone Fissure was excavated by William Beard, beginning in 1837. Both of these sites are important, but it is the third lost cave, the legendary Sandford Gulf, that most exercises the minds of cavers. It is hoped that this article will help to bring some clarity to proceedings, and through a process of elimination, propose a precise location for the missing Gulf - a very good place to start digging! Sandford Hill from the North-West Map data ©2016 Google ELEPHANT CAVE The full details of this mysterious cave were included in a letter dated 30 th January 1770, sent by William Jeffries of Wrington to The Rev.

North Somerset & Mendip Bats SAC Citation
EC Directive 92/43 on the Conservation of Natural Habitats and of Wild Fauna and Flora Citation for Special Area of Conservation (SAC) Name: North Somerset and Mendip Bats Unitary Authority/County: Bath and North East Somerset, North Somerset, Somerset SAC status: Designated on 1 April 2005 Grid reference: ST480544 SAC EU code: UK0030052 Area (ha): 561.19 Component SSSI: Banwell Caves SSSI, Banwell Ochre Caves SSSI, Brockley Hall Stables SSSI, Compton Martin Ochre Mine SSSI, King’s Wood and Urchin Wood SSSI, The Cheddar Complex SSSI, Wookey Hole SSSI Site description: The Cheddar complex and Wookey Hole areas support a wide range of habitats which provide feeding grounds for bats. These include semi-natural dry grasslands of which the principal community present is sheep’s-fescue – meadow oat-grass (Festuca ovina – Helictotrichon pratense) grassland which occurs on rock ledges and on steep slopes with shallow limestone soil, especially in the dry valleys and gorges and on the south-facing scarp of the Mendips. King’s Wood and Urchin Wood have developed over limestone which outcrops in parts of the site and forms a steep scarp to the south-east. There is mostly oak Quercus robur and ash Fraxinus excelsior woodland, though some areas are dominated by small-leaved lime Tilia cordata with both maiden and coppice trees. Other canopy trees include yew Taxus baccata, cherry Prunus avium and wild service tree Sorbus torminalis. There is a rich ground flora including many ferns and mosses. The limestone caves and mines of the Mendips and the north Somerset hills provide a range of important breeding and hibernation sites for lesser horseshoe bat Rhinolophus hipposideros and greater horseshoe bat Rhinolophus ferrumequinum. -

End of Pleistocene dusty - Temperature and CO2 - Milankovic Astronomical Climate Theory - Interglacials and other warm Periods - The Super volcano Toba - Links og literature Introduction Pleistocene is the period in Earth's history that we commonly refer to as the Ice Age. Through much of this period, the Earth's northern and southern regions were covered by kilometer thick glaciers. It is important to recognize that the Pleistocene was a series of real ice ages, separated by relatively short interglacial periods. The Pleistocene started 2.6 million years ago and lasted until the termination of the Weichsel glaciation about 11,711 years ago. Timeline of Earth's geological periods. Time progresses from right to left. The glowing inferno just after Earth was formed is named Hadean. In Archean water condensed and an atmosphere of nitrogen and methane was formed together with the first rocks that we know about. In Proterozoic cyano bacteria produced oxygen, which oxidized iron and methane, in the end of the period life emerged on the seabed. Phanerozoic represents the era in which there have been visible tangible life. It is divided in Paleozoic, Mesozoic and Cenozoic. Paleozoic was the period of early life. Mesozoic was the time of the dinosaurs, and Cenozoic is the era of mammals, which latter further is divided into Tertiary and Quaternary. -

Vegetation and Climate Changes at the Eemian/Weichselian Transition: New Palynological Data from Central Russian Plain
Polish Geological Institute Special Papers, 16 (2005): 9–17 Proceedings of the Workshop “Reconstruction of Quaternary palaeoclimate and palaeoenvironments and their abrupt changes” VEGETATION AND CLIMATE CHANGES AT THE EEMIAN/WEICHSELIAN TRANSITION: NEW PALYNOLOGICAL DATA FROM CENTRAL RUSSIAN PLAIN Olga K. BORISOVA1 Abstract. Palynological analysis of core Butovka obtained from the Protva River basin 80 km south-west of Moscow (55º10’N, 36º25’E) provides a record of vegetation and climate change in the central Russian Plain spanning the Last Interglacial and the beginning of the following glacial epoch. Pollen profiles of the Mikulino (Eemian) Interglaciation in the Central Russian Plain show a distinctive pattern of the vegetation changes, reflecting an increase in temperatures to- wards the optimum phase of the interglaciation followed by a gradual cooling. Rapid climatic deterioration, manifesting an onset of the Valdai (Weichselian) Glaciation, took place after a slower cooling accompanied by increasing humidity of climate during the post-optimum part of the Mikulino Interglaciation. The interglacial/glacial transition had a com- plex structure, being marked by a sequence of secondary climatic oscillations of varying magnitude. A decreasing role of mesophilic plants and an increase in abundance and diversity of the xerophytes and plants growing at present in the re- gions with highly continental climate in the Butovka pollen record suggests that during the Early Valdai the climate grew both more continental and arid. With this tendency at the background, two intervals of climatic amelioration can be dis- tinguished. Both of them are marked by the development of the open forest communities similar to the contemporary northern taiga of West Siberia. -
Ag'0 Proceeliing0. Where the Party Was Met by the Vicar, the Rev. AC
— 52 Fifty-seventh Annual Meeting. Cbiro s;?ag’0 Proceeliing0. On Thursday, the weather was again very beautiful and the members left Weston-super-Mare at 9.30 a.m. for Cfflotle Cturcft, where the party was met by the Vicar, the Rev. A. C. Harman. The Rev. E. H. Bates described the Church. He said : To the traveller on the upper road from Weston to Worle, the church presents a pleasing outline with its spire crowned tower, carved parapet over the north aisle, and external turret at the north-east corner. The distinctly marked break in the masonry of aisle and tower denotes two different periods of construction, and as the former is fifteenth century work, the tower is doubtless much older. There are, however, no archi- tectural features by which its exact age can be determined. The entrance -doorway on the south side is of a plain Korman type, perhaps of the same date as the font, which is assigned by Mr. Pridham to the period 1135 —^1154. A small window in the east wall of the porch may also belong to the original building. The arcade between the nave and aisle and the windows are all XV Century work. “ The fittings are of considerable interest. Besides the font, there is a stone pulpit w^hich has been moved from some other part of the church, as immediately behind it is a piscina. The altar to which this was appurtenant may have had some con- nection wdth the empty recess in the wall, probably intended for the recumbent effigy of some parishioner. -

A cluster analysis using the Received in revised form 8 August 2008 Bray–Curtis metric with single linkage to show relative faunal similarity was performed on successively Accepted 8 August 2008 older British mammalian faunas to investigate whether they become progressively different compared to the present day (Holocene). British mammalian faunas from MIS 3, 5, 11, 13 and 17 were compared with the Holocene revealing that the last glaciation (MIS 3) is more different than are any of the interglacials (MIS 5, 11, 13, 17). Furthermore, the interglacials generally become more distinct from the Holocene with age. This difference relates to the fact that interglacial faunas have greater proportions of extinct and extirpated species with increased age. The increase in extirpated taxa in turn relates to faunas becoming more non-analogue with greater age. The increase in extirpated elements with age probably relates to the individualistic response to climate change which appears to be progressing with time. -
An Attempt at Correlation of Main Climatostratigraphic Units of the Quaternary in the Marginal Zones of Continental Glaciations in Europe
ANNALES UNIVERSITATIS MARIAE CURIE-SKŁODOWSKA LUBLIN - POLONIA VOL.XLVIII, 14_____________________________ SECTIOB_____________________________________ 1993 Instytut Geologii Uniwersytetu Warszawskiego Leszek LINDNER, Leszek MARKS An Attempt at Correlation of Main Climatostratigraphic Units of the Quaternary in the Marginal Zones of Continental Glaciations in Europe Próba korelacji głównych jednostek klimatostratygraficznego podziału czwartorzędu w brzeżnej strefie zasięgu zlodowaceń kontynentalnych w Europie INTRODUCTION Studies of the Quaternary palaeogeographical evolution in the marginal zone of conti nental glaciations in Europe must be based on good knowledge of rhythmus of climatic changes in that time. Such changes in most cases were expressed by coolings that favou red development of 8 continental glaciations (Fig. 1) and warmings which were typical of climatic conditions during 7 interglacials, all during this part of the Quaternary that is na med the Pleistocene (Figs 2-4). From a climatostratigraphic point of view these glacia tions and interglacials, together with preceding main coolings and warmings of the Early Quaternary (Prepleistocene) as well as the following - the youngest warming of the Holo cene, are considered to be the main units of the inland Quaternary (M. D. Baraniecka 1990; L. Li n d n e r 1991b). These units are more and more frequently correlated with the 18O stages that record the main Quaternary climatic changes in deep-sea sediments (D.Q. Bowen 1989; D.Q. Bowen etal. 1989; L.Lindner 1984,1988a,b, 1991 a, b;F. Wiegank 1982; 1987; L. N. Voznyachuk 1985; V. A. Zubakov 1986, 1988, 1990; V. A. Zubakov and 1.1.
