<p>76 is striking for going notably deeper (in absolute terms) than anything
else apart from the lower reaches of Stellerweg.
</p>
<p>The caves under the <a href="../smkridge/">Schwarzmooskogel ridge</a>
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.
</p>
<p>These levels haven't been observed so clearly in the caves out under the
<a href="../plateau/">Loser Augst-Eck plateau</a> subarea, but Tony Malcolm
<a href="../years/1981/tmelev.htm">noted signs of them</a>. 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.
</p>
<p>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: Eislufth&ouml;hle is "Ice air cave" or "Ice breath
cave", while Schneewindschacht is "Snow wind shaft". 99 is noted as having
a "strong draught".
</p>
<p>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 <a
href="../../smkridge/161/top.htm">Kaninchenh&ouml;hle</a> and <a
href="../../smkridge/161/136.htm">Steinschlagschacht</a>. It would be very
interesting if there was significant horizontal development linking some of
the caves under the plateau with those under the ridge!

<h3>Eislufth&ouml;hle (1623/76)</h3>
<a href="../../plateau/76.html">Eislufth&ouml;hle</a> 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
<a href="76why.html">interesting</a>, so it's about time we had another
look.
<ul>
<li />The 76 description says "There are a number of going leads in this cave
and you're welcome to them". We've <a href="76qms.html">collated 8 of them</a>
from information in the log book writeups, published accounts, and surveys.
All but one of these are in Hall of the Green King (-260m) or above - the
proposal is to allocate enough tackle to 76 to enable us to get to this level.
Judging from CUCC's experience reexploring
<a href="../../smkridge/161/136.htm">Steinschlagschacht</a> and Arge's
looking at old CUCC finds in the Stellerweg area, there are likely to also
be a number of undocumented or previously unnoticed leads.
<li />Eislufth&ouml;hle was surveyed to about -150m in 1976 (Waddington: <i>"I
would not claim more than grade 2, in the light of subsequent surveying
experience"</i>). The survey below -150m is almost entirely based on rope
and ladder lengths. Perhaps unsuprisingly, the published surveys are
missing horizontal passages in places where they're described in write-ups!
None of the original data survives anyway, so we should try to produce a decent
survey of the known cave as well as mapping new finds.
<li /><a href="../../plateau/99.htm">99</a> is a strongly draughting entrance
about 35m from 76 which was explored to a <i>"ledge with a 1m diameter shaft
dropping in a corkscrew at least 20m."</i> (at perhaps -40m).
<a href="../../years/1979/report.htm#89">Contemporary reports</a> suggest
<i>"It is not clear how [99] relates to 106, but if it does come into 106 then
it must do so fairly far down."</i> (106 was another number allocated to 76
initially).
<li />If we exhaust 76, <a href="../../plateau/97.htm">Schneewindschacht</a>
is in the same area. Waddington: <i>"if you want a cave with some real
potential to go in a big way, I'd suggest a return to 97 - Schneewindschacht.
This has a wide open phreatic tunnel in it, which could be easily gained with
the aid of a rock drill. A rock drill might also be of use in making the Nun's
C*nt a bit more amenable"</i>.
