Why Eislufthöhle?

+ +

+This shows the caves in the area with 4 additional fake vertical shafts +indicating the entrance locations and depths of (from left to right) +97 (Schneewindschacht), +76 (Eislufthöhle) +107 (Gemshöhle), and +82 (Bräuninghöhle): +

+ + +
+[Download 3d file of this] + +

76 is striking for going notably deeper (in absolute terms) than anything +else apart from the lower reaches of Stellerweg. +

+ +

The caves under the Schwarzmooskogel ridge +show definite levels of major horizontal phreatic development. These can be +seen to some extent in the screenshot above, but they're clearer if you play +around with the survey in Aven. The Austrian cavers tell us that corresponding +phreatic levels are seen in many caves all over the surrounding parts of +Austria, so there are good reasons to think they're not a phenomenon only +associated with this ridge. +

+ +

These levels haven't been observed so clearly in the caves out under the +Loser Augst-Eck plateau subarea, but Tony Malcolm +noted signs of them. Exploration in +the early years of CUCC in Austria followed a pattern of "drop pitches +to a sump or other conclusion, derig, try another entrance" - the major +horizontal levels under the ridge were mostly found much more recently +once we got a bit more thorough. +

+ +

A particularly notable feature of a number of the caves in this area +is strong outward draughts (in Summer at any rate). The very names of +the caves indicate this: Eislufthöhle is "Ice air cave" or "Ice breath +cave", while Schneewindschacht is "Snow wind shaft". 99 is noted as having +a "strong draught". +

+ +

Wildly hypothesising for a moment, this might indicate air coming from +higher entrances, in the same way that the strongly draughting entrances on the +East side of the Schwarzmooskogel ridge are most likely due to airflow through +from the higher entrances of Kaninchenhöhle and Steinschlagschacht. It would be very +interesting if there was significant horizontal development linking some of +the caves under the plateau with those under the ridge! +

Eislufthöhle (1623/76)

+ +Eislufthöhle was found on the second +ever CUCC expedition to the Loser area in 1977. That year the explorers got +to -150m with the way on wide open. They pushed again in 1978, and in 1979 +finally reached a sump at approximately -506m. They derigged and nobody has +been back in the intervening quarter of a century. The area is +interesting, so it's about time we had another +look. + + + +
