45 Jahre ist es her, dass Fritz Loretan und seine Freunde sich der Herausforderung an der überhängenden Felswand stellten. Lange hat der Geltenbach geruht und seine Geheimnisse lagen im Dunklen. Welches heute die Herausforderungen an diesem Projekt sind, zeigt Hansueli Kallen zusammen im Doppelvortrag mit Fritz Loretan.
Contrary to the Schratteflue with their widely visible karrenfields, the karst of the Helvetic boarder chain lies hidden and is extending from the Schratteflue further northeast across Schafmatt, Schimberig to Pilatus. In this area, the extended outcrops of the «Lower Schrattenkalk» are only visible in the northward slope of the rock walls. Continue reading “Karst und Höhlen der Randkette im Entlebuch”
From Giswil only the «Drachenloch» was known in the cave cadastre. Although the area, apart from the Giswilerstock, has little karst, mythology suggests that there should be more caves. As part of the Obwaldner Cave and Karst Landscape Inventory (HKI), twelve caves were discovered in 2017 and 2018, not least thanks to literature research and intensive field work. Continue reading “Sagenhafte Höhlen zwischen Giswilerstock / Brienzer Rothorn”
Since the opening of the cave for non-divers the total surveyed length of the Bärenschacht has been more than doubled. Significant new parts of the cave could have been found thanks to systematic exploration. Furthermore the cave was pushed towards north by successfully penetrating the big North-Sump that measures now 450m. Continue reading “Bärenschacht – von 36 km auf über 82 km”
After the successful dive through the North Siphon, the connection with the large karst system “Réseau Siebenhengste-Hohgant” is within reach. After several research tours in 2018, to the North Siphon, which is almost 1,000 metres lower, a 6-day expedition could again be carried out over New Year’s Eve. Continue reading “Bärenschacht, Nordsiphon Tauchvorstoss die 3.”
The Seefeldhöhle (Seefeld cave, also called Tropfloch) extends in a layer of sandstone of the Sieben Hengste, a mountain situated in the centre of Switzerland, north from the Lake of Thun. This cave forms an astonishing labyrinth and runs across a hill just underneath the surface. It has been walked through for over a hundred years and is a very appreciated excursion goal of the local population.
The caves of the Hohlaub are shafts or fractures becoming too narrow, at best at -200m, much more often at about -20m. All? No, because one irreductible cave has resisted to the gravity. Continue reading “Le Hohlaub phréatique”
The Sägistal valley is a remote high valley in the Bernese Prealpes with typical karst phenomena. The exploration of caves started in the 1970ies by the SGH-Interlaken and is coordinated since 1988 by the International Alpine Karst Group (ISAAK) with support of numerous international speleo clubs. More than 400 caves have been documented with the “Oberländer-Chessiloch” system the largest one (2346 m length, −488 m depth).
In August 2010 the joint explorers of the Association of Cavers of the Hohgant Region (HRH) was given a new access in the formerly deepest and remotest areas of the huge “Réseau Siebenhengste-Hohgant”. Since then the “Zone Profonde” (ZP) was ‘rediscovered’, rolled up systematically and new discoveries reported in almost every direction.
