Publisher National Institute of Polar Research 10-3, Midori-cho, Tachikawa-shi, Tokyo 190-8518, Japan Editors Kazuyuki Saito Mamoru Ishikawa Preface The second Asian Conference on Permafrost (ACOP 2017) was convened at Hokkaido University, Sapporo, Japan, July 2-6. The conference organizers and co-sponsors were the Arctic Research Center, Hokkaido University, Japanese Society of Snow and Ice, Tokyo Geographical Society, Sapporo Convention Center, Kajima Co., Shimizu Co., Meiwafosis Co., LI-COR, Chemical Grouting Co., Seiken Co., Cubic-I Co., Campbell Scientific, Climate and Cryosphere (CliC), Arctic Challenge for Sustainability (ArCS), and the International Permafrost Association (IPA). A total of 180 participants from 18 countries including accompanying persons attended: Austria (1), Canada (7), China (62), Denmark (1), France (4), Germany (5), Hong Kong (2), Indonesia (1), Japan (55), Mongolia (6), Norway (18), Portugal (2), Republic of Korea (2), Russia (23), Slovenia (1), Switzerland (2), and the USA (6). The ACOP 2017 LOC provided travel grants to 20 persons including young researchers and keynote speakers. The sessions covered all aspects of frozen ground research, from needle ice to deep permafrost, from frozen ground engineering in cities to permafrost on volcanoes, and from links between frozen ground and ancient cultures to present-day outreach. The daily sessions started with plenary talks from senior and young keynote speakers: Tazio Strozzi (Switzerland), Norikazu Matsuoka (Japan), Kabir Rasouli (Canada), Arne Instanes (Norway), Hisao Izuta (Japan), Sonia Tomaskovicova (Denmark), Anna Liljedahl (USA), and Jens Strauss (Germany). A total of 86 oral and 55 poster submissions were presented in a series of two concurrent sessions. In the first day of the conference, a joint workshop between the IPA’s Mapping Initiative and GlobPermafrost took place to discuss current conditions and future collaboration on permafrost mapping and remote sensing. On the same day, Arctic adventurer Yasunaga Ogita and Professor Emeritus at Hokkaido University, Masami Fukuda, kindly provided general lectures to the public at the museum of Hokkaido University. The abstracts submitted to the conference were compiled, and distributed in a USB memory to the participants at the registration. After the conference, however, we received a number of enquiries from those who could not attend the conference, asking for publication of the ACOP2017 abstracts in a more accessible and citable form. The local organizing committee of the ACOP2017 decided, following internal discussions, that we should publish with a doi. Finally, total of 141 abstracts were published in this Book of Abstracts, ACOP2017. - Kazuyuki Saito and Mamoru Ishikawa, 2020.

  • Moroccan Climbing: Rock, Sun and Snow
    PAUL KNOTT Moroccan Climbing: Rock, Sun and Snow OroCCO fascinates me. It has a rich complexity, retaining an alluring M mystique despite being well travelled and documented. During 1998 and 1999 I was lucky enough to get a real insight into the country and its climbing through a post at the delightful Al Akhawayn University in the Middle Atlas Mountains. Here I give a flavour of the rock climbing, skiing and mountain walking, all of them spiced with the cultural interest inherent in Morocco's mountain country. After three days' driving from the UK, I sped through dry limestone plateaux to Ifrane with its promise of sunshine and snow. I found myself sharing an office with Michael Peyron - Alpine Club member, Atlas guidebook author and Berber expert. Along with other companions, we escaped at weekends to explore the wealth of lesser-known mountains a short drive from the fairy-tale campus. We sought and found crags and mountains with European-style ease of access. For big, unexplored rock climbs one of my favourite places was the Dades Gorge. This was visited by Trevor Jones and Les Brown in 1990, but otherwise seems to have seen little or no climbing. Above Boumalne-de­ Dades the valley becomes strikingly beautiful, with its kasbahs and its unusual rock features (doigts de singes or monkey fingers) set amongst emerald green jardins. On my first visit we got no further than this; the downpour sent raging torrents across the road and stranded us at Ait-Arbi. We found the doigts disappointing for climbing. I returned some weeks later, to the gorge itself.

  • Quaternary Deposits and Landscape Evolution of the Central Blue Ridge of Virginia
    Geomorphology 56 (2003) 139–154 www.elsevier.com/locate/geomorph Quaternary deposits and landscape evolution of the central Blue Ridge of Virginia L. Scott Eatona,*, Benjamin A. Morganb, R. Craig Kochelc, Alan D. Howardd a Department of Geology and Environmental Science, James Madison University, Harrisonburg, VA 22807, USA b U.S. Geological Survey, Reston, VA 20192, USA c Department of Geology, Bucknell University, Lewisburg, PA 17837, USA d Department of Environmental Sciences, University of Virginia, Charlottesville, VA 22904, USA Received 30 August 2002; received in revised form 15 December 2002; accepted 15 January 2003 Abstract A catastrophic storm that struck the central Virginia Blue Ridge Mountains in June 1995 delivered over 775 mm (30.5 in) of rain in 16 h. 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.

  • Climbing in the Atlas Mountains a Survey
    HAMISH BROWN Climbing in the Atlas Mountains A Survey (Plates 24-27) magine a country with eighty per cent sunshine throughout the year, I grand mountain scenery, its rock climbing potential barely touched, all within easy reach, with no political hassles orcostly fees, and a lovely people. It may sound too good to be true but it all exists in Europe's nearest truly exotic foreign country: Morocco. The Atlas Mountains, which sweep across from north-east to south-west, separating 'the desert and the sown', offer a climber's paradise. Quite why the Atlas has suffered neglect by climbers from Britain is hard to understand. Perhaps the names are too difficult - there's no kudos in reporting unpronounceable climbs - or the information is hidden away in French publications. 1 Time the cat escaped from out of the bag. I spent a winter in the Atlas in 1965 and repeated this delight in 1966. Having gone there specifically to climb (Notes in AJ 1966) I ended simply hooked on the whole Atlas ambience and began to wander rather than be restricted to one area. The natural outcome of this was an end-to-end trek 2 in 1995 : 96 days, 900 miles and about 30 peaks bagged. Farfrom rounding off my knowledge, the trip introduced me to a score of new worthy areas to visit and I've had five Atlas months every year since. 3 The scope for climbing is vast. The country must have 50 limestone gorges, miles long and up to 2000 feet deep, each ofwhich would fill volumes ofclimbs if located in Europe, while on the mountains there are crests to be traversed and notable granite faces still virgin.

Subject Editor: Jadranka Rota. Abstract. The type specimens of Sesia sirphiformis Lucas, 1 849 from Lac Tonga in Algeria and Dipso- sphecia megillaeformis v. tunetana Le Cerf, 1 920 syn. n. from the vicinity of Tunis were examined and found to be conspecific. Bembecia sirphiformis belongs to the B. ichneumoniformis (Denis & Schiffer- müller, 1775) species group and is currently known only from northern Africa. Records from Sicily, Sar- dinia, Corsica, southern Italy, and Morocco (as B. tunetana) are here considered doubtful and may belong to other species. B. astragali (Joannis, 1909) stat. rev., which was described from northern Spain and southern France and was previously considered conspecific with B. sirphiformis, actually appears not to be so closely related to B. sirphiformis and seems to belong to the B. megillaeformis (Hübner, 1813) spe- cies group. B. igueri Bettag & Bläsius, 1998 syn. n. from Morocco is now considered to be a synonym of B.

Box 227, Reading, RG6 6AB. 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 . (1995) indicate that during frozen ground, however, either seasonal or perennial, have not Marine Oxygen Isotope Stage (OIS) 6, permafrost extension was rather previously been documented outside Alderney.
