<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="../../1623/">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="../../1623/">Loser Augst-Eck plateau</a> subarea, but Tony Malcolm
|
|
<a href="../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: Eislufthöhle is <i>"Ice air cave"</i> or
|
|
<i>"Ice breath cave"</i>, while Schneewindschacht is <i>"Snow wind shaft"</i>.
|
|
99 is noted as having a <i>"strong draught"</i>.
|
|
</p>
|
|
|
|
<p>Wildly hypothesising for a moment, this might indicate air coming through
|
|
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="../../1623/161/top.htm">Kaninchenhöhle</a> and
|
|
<a href="../../1623/161/136.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!
