The deluge triggered more than 1000 slope failures; and stream channels and debris fans were deeply incised, exposing the stratigraphy of earlier mass movement and fluvial deposits. The synthesis of data obtained from detailed pollen studies and 39 radiometrically dated surficial deposits in the Rapidan basin gives new insights into Quaternary climatic change and landscape evolution of the central Blue Ridge Mountains. The oldest depositional landforms in the study area are fluvial terraces. Their deposits have weathering characteristics similar to both early Pleistocene and late Tertiary terrace surfaces located near the Fall Zone of Virginia. Terraces of similar ages are also present in nearby basins and suggest regional incision of streams in the area since early Pleistocene–late Tertiary time. The oldest debris-flow deposits in the study area are much older than Wisconsinan glaciation as indicated by 2.5YR colors, thick argillic horizons, and fully disintegrated granitic cobbles.

  • Glenlude Management Plan
    Management Plan Glenlude Estate 2012-2017 Introduction 1. Background Glenlude Estate is approximate 6 miles south of Innerleithen on the B709, in the Scottish Borders. It is a relatively small property of 140 ha The Glenlude estate was gifted to the John Muir Trust in 2004 by the late Shelia Bell who retained a life time tenancy until her death in November 2010. Sheila Bell had purchased the property in two roughly equal parts during 2000. These were Glenlude Forest (formally Kirkhouse) which had been planted by the Forestry Commission in 1995 and the open hillside of Glenlude hill farm as well as a strip of land on the west of the B709. Prior to 1995 both sections had been managed together as rough sheep pasturage within Glenlude hill farm. The John Muir Trust took over day to day management of Glenlude upon Sheila Bells death and included it in the remit of the East Schiehallion Conservation Manager post on its creation in March 2011. In March 2012 the Trust appointed a part-time conservation ranger to be based at Glenlude. 2. Vision for Glenlude Estate The John Muir Trust intends to manage Glenlude in line with its vision for wild land to support natural habitats and species. The Trust wishes to create and support a diverse landscape of native woodland, sustainable numbers of grazing animals, rich flora and abundant wildlife. These are defined with in the Trusts Wild Land Management Standards at www.wildlandmanagement.org.uk During the process of creating this diverse landscape the Trust intends to maximise opportunities for the involvement of volunteers at all stages.

In 2009, in partnership with the National Park Authorities, this work was extended to determine the special qualities of the two National Parks, including the National Scenic Areas within them. The result of the work for the Loch Lomond and the Trossachs National Park is reported here. Main findings • The park is large and diverse with significantly different landscape characteristics in different areas. Hence as well as listing the landscape qualities which are generic across the park, the qualities for the four landscape areas of Argyll Forest, Loch Lomond, Breadalbane and the Trossachs are also given.

INTRODUCTION If permafrost extent is a good indicator of the intensity of cold climates, then the ice wedge casts and sand and gravel wedges found in Following the recognition of periglacially induced macro-scale northern France, particularly in Brittany, demonstrate former sedimentary structures and fabrics of deposits of Last Glacial age on Pleistocene cold environmental conditions having extended into that Alderney, a search for analogous features on Guernsey and Jersey has region (van Vliet-Lanë, 1996; van Vliet-Lanoë et al ., 1997). The been undertaken. It has long been known that cold climate related chronology for such periglacial conditions in Brittany, however, mass wasting deposits (head) and aeolian deposits (loess) are common suggests a rather earlier date than for southwest England and the throughout the Channel Islands. Structures specifically related to Channel Islands. For example, Loyer et al .

  • Southern Scottish Hill Generics: Testing the Gelling and Cole Hypothesis
    Southern Scottish Hill Generics: Testing the Gelling and Cole Hypothesis Peter Drummond University of Edinburgh Gelling and Cole have argued for English hill-names (specifically those incorporated into settlements) that the different generics represent different topographies or shapes all across the land. Their hypothesis is important enough to quote in detail: ... groups of words which can be translated by a single modern English word such as ‘hill’ or ‘valley’ do not contain synonyms. Each of the terms is used for a different kind of hill, valley or whatever ... The key to Anglo-Saxon topographical naming lies in the precise choice of one of the many available words for ... hills ... these names represent a system which operated over most of England ... [except] the south-west peninsula, where English speech arrived several centuries later ...1 Is this true of Scots hill-generics too? Can we have a valid typology of hill-generics applying across southern Scotland, in the way that Gelling and Cole have done for most of England—although their work is on hill toponyms that have been taken into settlement names, by definition lower hills?2 Pratt has attempted a small-scale application of Gelling and Cole’s methodology to settlements in southern Scotland, and her tentative conclusion, on this limited sample, was that their interpreta- tion of six of the nine elements might be supported in this area.3 The nine elements she chose to explore were limited to Old English,4 and 1 M.

  • Cryogenic Fracturing of Calcite Flowstone in Caves: Theoretical Considerations and Field Observations in Kents Cavern, Devon, UK

Joyce Lundberg1 and Donald A. McFarlane2 Abstract: Lundberg J. and McFarlane D. 2012. Cryogenic fracturing of calcite flowstone in caves: theoretical considerations and field observations in Kents Cavern, Devon, UK. International Journal of Speleology, 41(2), 307-316. Tampa, FL (USA). ISSN 0392-6672. http://dx.doi.org/10.5038/1827-806X.41.2.16 Several caves in Devon, England, have been noted for extensive cracking of substantial flowstone floors. Conjectural explanations have included earthquake damage, local shock damage from collapsing cave passages, hydraulic pressure, and cryogenic processes. Here we present a theoretical model to demonstrate that frost-heaving and fracture of flowstone floors that overlie wet sediments is both a feasible and likely consequence of unidirectional air flow or cold-air ponding in caves, and argue that this is the most likely mechanism for flowstone cracking in caves located in Pleistocene periglacial environments outside of tectonically active regions. Modeled parameters for a main passage in Kents Cavern, Devon, demonstrate that 1 to 6 months of -10 to -15° C air flow at very modest velocities will result in freezing of 1 to 3 m of saturated sediment fill. The resultant frost heave increases with passage width and depth of frozen sediments. In the most conservative estimate, freezing over one winter season of 2 m of sediment in a 6-m wide passage could fracture flowstone floors up to ~13 cm thick, rising to ~23 cm in a 12-m wide passage.

  • Scottish Natural Heritage FACTS and FIGURES 1996-97
    Scottish Natural Heritage FACTS AND FIGURES 1996-97 Working with Scotland’s people to care for our natural heritage PREFACE SNH Facts and Figures 1996/97, contains a range of useful facts and statistics about SNH’s work and is a companion publication to our Annual Report. SNH came into being on 1 April 1992, and in our first Annual Report we published an inventory of Sites of Special Scientific Interest (SSSIs). After an interval of five years it is appropriate to now update this inventory. We have also provided a complete Scottish listing of National Nature Reserves, National Scenic Areas, European sites and certain other types of designation. As well as the information on sites, we have also published information on our successes during 1996/97 including partnership funding of projects, details of grants awarded, licences issued and our performance in meeting our standards for customer care. We have also published a full list of management agreements concluded in 1996/97. We hope that those consulting this document will find it a useful and valuable record. We are committed to being open in the way we work and if there is additional information you require, contact us, either at any local offices (detailed in the telephone directory) or through our Public Affairs Branch, Scottish Natural Heritage, 12 Hope Terrace, Edinburgh EH9 2AS.
