The Alpstein in Three Dimensions: Fold-And-Thrust Belt Visualization in the Helvetic Zone, Eastern Switzerland
Swiss J Geosci (2014) 107:177–195 DOI 10.1007/s00015-014-0168-6 The Alpstein in three dimensions: fold-and-thrust belt visualization in the Helvetic zone, eastern Switzerland Paola Sala • O. Adrian Pfiffner • Marcel Frehner Received: 14 August 2013 / Accepted: 9 September 2014 / Published online: 11 December 2014 Ó Swiss Geological Society 2014 Abstract To investigate the geometrical relationships determined from line-length balancing. The model also between folding and thrust faulting, we built a 3D geo- clearly shows the lateral extension, the trend, and the logical model of the Helvetic fold-and-thrust belt in eastern variation in displacement along the principal faults. The Switzerland from several existing and two newly drawn reconstruction of horizons in 3D allows the investigation of cross-sections in the Sa¨ntis area. We partly redrew existing cross-sections in any given direction. The 3D model is cross-sections and validated them by checking for line useful for developing and understanding how the internal length balance; to fill areas with no data we drew additional nappe structures, namely folds and thrust faults, change cross-sections. The model was built based on surface along strike due to palaeogeographic and stratigraphic interpolation of the formation interfaces and thrusts variations. Lateral stratigraphy variations correlate with between the cross-sections, which allowed generating eight different deformation responses of the nappe. Changes can main surfaces. In addition, we used cave data to validate occur either abruptly across transverse faults or in a more the final model in depth. The main structural elements in gradual manner. the Sa¨ntis area, the Sa¨ntis Thrust and the Sax-Schwende Fault, are also implemented in the model. -
The Matterhorn Centenary
TI-IE MATTERHORN CENTENARY THE MATTERHORN CENTENARY BY B. R. GOODFELLO'IV (Five illustrations: nos. 50- 54) DWARD WHYMPER must have appreciated in his lifetime that his ascent of the Matterhorn and his own dramatic account of the ............. disaster had added immeasurably to the glamour of that incom parable mountain. So he must have realised the great contribution which he made personally to the greater prosperity of the people of Zermatt; they have long acknowledged this and the centenary was closely linked with Whymper"s name. But he could scarcely have foreseen the impact of to-day's mass affluence, of the rise of ski-ing and of universal publicity on the Alpine village he had known first over 100 years ago. We had all expected for some years that the centenary of the Matter horn ascent would be used by Zermatt for publicity on the grand scale. With the true mountain lovers' distaste for the prostitution of the Alps for commercial ends, many decided to keep away in 1965. But by doing so they missed a great occasion. For, although the Festival Week was unashamedly dedicated to Zermatt propaganda, the whole of the func tions were conducted in the very best of taste. Above all Zermatt, for this week, was the meeting place for mountaineers from all over Europe and from America, India and further afield. Enjoying the warm and generous hospitality of our Swiss hosts, we made many valuable new friendships and renewed old ones. The Alpine Club came in some strength, more than fifty in number, many with their wives and some with their families. -

One of the finest long-distance trekking opportunities in Alpine Europe is the walking circuit of the huge, many-summitted massif of Monte Rosa (4634m) in the Swiss Alps. Starting out from the picturesque Alpine village of Saas Fee, our walking follows a clockwise direction, crossing from Switzerland then trekking into Italy and then back again. This undiscovered gem of a walking route around Monte Rosa keeps to the high ground as much as possible, close up beneath towering Alpine peaks, crossing airy passes and encountering snowfields and even walking over glaciers. En route, there are stunning views of many of the big peaks of the Alps, such as the Dom (4545m) Weisshorn (4596m) and particularly memorable Matterhorn (4478m). -
One Hundred Years Ago (With Extracts from the Alpine Journal)
CA RUSSELL One Hundred Years Ago (with extracts from the Alpine Journal) (Plates 57-61) he fIrst attempt to ascend Mont Blanc in the twentieth centuryl was T made on Thursday, but without success. Even before the Pierre Pointue was reached the snow was found to be so deep that racquettes had to be used, while at the Grand Junction of the Glacier de Taconna progress was rendered very difficult from the same cause. On reaching Grands Mulets (10,007 feet), it was decided to give up the task of reaching the actual summit owing to the great depth of the snow and the intense cold, and signs ofwind. Moreover, one of the guides was suffering from frostbite. The party, consisting of Mr. Crofts and the guides Joseph Demarchi, Fran~ois Mugnier and Jules Monard spent the night at the Grands Mulets, and descended to Chamonix next morning. The severe conditions experienced by Mr Crofts' party on 17 January 1901 were prolonged by exceptionally cold winds which persisted for several weeks in many Alpine regions. Although little mountaineering was possi ble the fust ski ascents of two peaks were completed: on 30 March Henry Hoek and Ernst Schottelius climbed the Dammastock; and on 28 May Schottelius, accompanied by Friedrich Reichert, reached the summit of the Oberaarhorn. A period of fine weather which commenced in May prompted an early start to the climbing season and by the end of the fIrst week in June a number of successful expeditions had been completed. Throughout Switzerland glorious, warm weather is being experienced, and with it Alpine climbing has begun in real earnest. -

Photo Chaggar collection … or as Andy kindly opined: One old codger, a (relatively) young tyke and a few big hills! This summer, Andy Tomlinson and I undertook what has become, in recent years, our annual ‘boys trip’ to the Alps, and this year we had chosen an early season window with the hope of putting his new Viper axes to good use on some classic snow/ice routes such as the Dreieselwand on the Lenzspitze and the Whymper Couloir on the Aiguille Verte. Many weeks of flicking through guides and glossy coffee-table Alpine books, exchanging multiple e-mails with tick-lists and logistics and deliberating over the optimum selection of ropes had served only to build excitement and expectation of the journey ahead. An obsessional fascination with the jet stream and weather charts revealed we were likely to be blessed with stable high pressure across much of the Alps but the final call on our destination would be left until the last weather check on the midnight ferry from Dover. Despite initial plans of climbing in the Oberland to tick the mighty Lauteraahorn, Finsteraahorn and Eiger, the seduction of wall-to-wall sunshine in Chamonix proved too much to resist and after an overnight drive we found ourselves in the familiar Carrefour in Sallanches, stocking the trusty campervan with vital supplies (beer, cheese, salami and a new camera for Andy as the new one he had brought to the Alps was too 10 TWO OLD CODGERS AND A FEW BIG HILLS nice to take on a proper hill, although it was many months before this expense was declared to finance control in Stoke). -
Grand Combin Xxx July, 2019
Grand Combin 4314 Meters 22-23 July 2019 Guides: Rütschi Pollinger and Thomi Zumtaugwald Situated east of the Mont Blanc massif, west of the Matterhorn, north of Aosta and south of the Rhone, Grand Combin is not among the most prominent, but is certainly one of the more remote peaks on the Swiss- Italian border. We accessed the area from the St. Bernard Pass road. After you turn off at Bourg St. Pierre and head into the countryside, it’s a long hike through winding valleys to get to the hut, Cabane de Valsorey. Our hut-climb day is very hot. We and our guides have driven from the Saas Valley in 2 cars. There is very little roadside parking. Rütschi and Thomi park their car in a farmyard, right at the trailhead. Here’s JC setting off above the farm. The walk from our parking spot at 1850 m to the hut at 3037 m takes about 4 hours. The whole 6.5 km are in unrelenting sun. We allow ourselves one short snack break and a longer lunch break just 45 minutes from the hut. Our Grand Combin tour tomorrow will include two separate 4000 m peaks, connected by a snow ridge. Reaching the first peak - just visible under the cloud here - requires a long stretch of rock climbing, some on bad and some on good rock. You can see the rock section, rising sharply from left to right; the hut is above us to the left. And here is the whole tour! We will leave the hut (not visible), climb the Arete du Meitin to the first peak (Combin de Valsorey, 4184 m), and finally the steep snow ridge to the second peak (Combin de Grafeniere, 4314 m).
