<h2>Description</h2>
|
2004-05-09 10:09:11 +01:00
|
|
|
<p>The entrance, a bedding plane unblocked because of a draught,
|
|
|
|
|
gives access to a series of short pitches, dry at the start, which
|
|
|
|
|
get bigger, deeper, wider and wetter. The first exploration of 1976
|
|
|
|
|
had reconnoitred to -200m to the base of a 40m pitch (<b>The Black
|
|
|
|
|
Hole</b>). The explorers of this year started on the descent of a
|
|
|
|
|
fine 60m pitch of constant shape, slightly sloping. At the bottom
|
|
|
|
|
of this is the only chamber of the cave : <b>The Galactic Hall</b>.
|
|
|
|
|
Here the cave splits into two routes, the active and the
|
|
|
|
|
fossil.</p>
|
2001-08-15 19:29:27 +01:00
|
|
|
|
|
|
|
|
<h3>Active system</h3>
|
2004-05-09 10:09:11 +01:00
|
|
|
<p>Downstream from the chamber a drop leads to a small chamber
|
|
|
|
|
among boulders, the <b>Love Nest</b>. (No idea who ventured to call
|
|
|
|
|
it this[?]) Between the boulders a 20m pitch opens, immediately
|
|
|
|
|
followed by a 25m pitch. In fact, the last 25m of descent drops
|
|
|
|
|
between the walls of an immense aven to land on a flat gravel
|
|
|
|
|
floor. A diagonal chimney leads to a trickle of water.</p>
|
|
|
|
|
<p>A fissure marks the start of the <b>Anti-matter meander</b>,
|
|
|
|
|
where one immediately rejoins the underground stream. This has an
|
|
|
|
|
average flow of two litres per second but quite rapidly increases
|
|
|
|
|
to 10-15 litres per second in flood. The first part of the meander
|
|
|
|
|
is straight and interrupted by 3 small pitches and two drops. At
|
|
|
|
|
the top of the first, in the roof, is the connection with the
|
|
|
|
|
fossil system. Quickly, the meander becomes less amenable: high and
|
|
|
|
|
narrow, it is plastered with mud (the anti-matter) which makes
|
|
|
|
|
progress quite arduous. Three pitches of 5, 14 and 10, punctuate
|
|
|
|
|
progress. This last, followed by a drop of 3m, gives access to a
|
|
|
|
|
section of passage blocked by clay. At the end of this, the stream
|
|
|
|
|
disappers into a fissure with tight impenetrable bends. The passage
|
|
|
|
|
is continued by a quite large fossil branch. After some 50m, the
|
|
|
|
|
draught goes into an earthy hole, the start of a big pitch of 70m
|
|
|
|
|
in several stages.</p>
|
|
|
|
|
<p>Halfway down, the pitch is rejoined by the stream which is
|
|
|
|
|
avoided by a parallel fossil pitch. There immediately follows
|
|
|
|
|
another pitch of 55m, totally wet and characterised by an
|
|
|
|
|
elliptical cross-section and constant slope. At the bottom, the
|
|
|
|
|
water is engulfed by a fissure about three metres long, followed by
|
|
|
|
|
a tight meander which we haven't pushed.</p>

|
|
|
<h3>Fossil system</h3>
|
2004-05-09 10:09:11 +01:00
|
|
|
<p>Upstream from the Galactic Hall, a window some metres high gives
|
|
|
|
|
access to a good-sized passage (3x3m on average), the <b>Little
|
|
|
|
|
Green Men's passage</b>. One comes up against a climb of 3m at the
|
|
|
|
|
base of which the trickle of water is lost into a meander cut below
|
|
|
|
|
the fossil passage (see below). After a narrowing and a climb, the
|
|
|
|
|
passage ends in boulders between which it is still possible to
|
|
|
|
|
penetrate for a dozen metres.</p>
|
2001-08-15 19:29:27 +01:00
|
|
|
<p>Back in the meander below the fossil passage: this ends at the
|
2004-05-09 10:09:11 +01:00
|
|
|
<b><span lang="fr" xml:lang="fr">Gomette</span> pitch</b>
|
|
|
|
|
(discovered by the <span lang="fr" xml:lang="fr">Gaumais</span>), a
|
|
|
|
|
60m pitch, spray-lashed in its lower part by "the wee-wee". At the
|
|
|
|
|
base of this pitch is the beginning of the <b>Mutants' meander</b>.
|
|
|
|
|
This is a passage for masochists <span lang="fr" xml:lang="fr">par
|
|
|
|
|
excellence</span>: at the bottom, tight and suit-snagging. It ends
|
|
|
|
|
in a series of climbs and a 30m pitch joining the active
|
|
|
|
|
system.</p>

<h2>Geology</h2>
|
|
|
|
|
<h3>General</h3>
|
2004-05-09 10:09:11 +01:00
|
|
|
<p>From the geological point of view, the <span lang="fr" xml:lang=
|
|
|
|
|
"fr">Gouffre Ovni</span> is a typical example of the karstic
|
|
|
|
|
phenomena of the massif, and likewise of the greater part of the
|
|
|
|
|
karst of Austria. There isn't a zone of pitches leading to a
|
|
|
|
|
master-cave on an impermeable bed (of the Pyrenean type) nor tight
|
|
|
|
|
vertical caves (of the <span lang="fr" xml:lang="fr">Vercors</span>
|
|
|
|
|
or <span lang="fr" xml:lang="fr">Chartreuse</span> type). The
|
|
|
|
|
primary factors in the formation are the intense orogenic
|
|
|
|
|
fracturing combined with a very wet climate and heavy snow-falls
|
|
|
|
|
since the start of the era.</p>
|
2001-08-15 19:29:27 +01:00
|
|
|
<p>These caves generally open by virtue of the simple form of the
|
2004-05-09 10:09:11 +01:00
|
|
|
discontinuities in the limestones (joints, bedding-planes). Then
|
|
|
|
|
they enlarge more and more by following the larger-scale phenomena
|
|
|
|
|
(faults, master-joints). The master-cave, when it exists, is
|
|
|
|
|
generally only short and near the resurgence.</p>
|
|
|
|
|
<h3 lang="fr" xml:lang="fr">Gouffre Ovni</h3>
|
|
|
|
|
<p>The entrance is in a bedding plane open for about two metres.
|
|
|
|
|
There follows a series of pitches, quite small, formed in a quite
|
|
|
|
|
sinuous joint and enlarged on bedding planes and very strong
|
|
|
|
|
[<span lang="fr" xml:lang="fr">pendage</span> - dictionary failure]
|
|
|
|
|
in this zone. At about -200m, the influence of another factor
|
|
|
|
|
starts to be felt. The pitches become bigger and bigger and the
|
|
|
|
|
walls cleaner and cleaner. This section is characterised by a fault
|
|
|
|
|
running roughly East-West (see figure 1).</p>

<p>This fault controls the major part of the formation of the cave.

|
|
|
|
|
<p>As we have already said, there is a strong draught which drew
|
|
|
|
|
our attention to Ovni. This draught was blowing in a hot period
|
|
|
|
|
(summer) [so] we logically [expected] to find the presence of an
|
|
|
|
|
intermediate entrance. Seeing the strength of the cold draught
|
|
|
|
|
[<span lang="fr" xml:lang="fr">chassé</span>], the existence
|
|
|
|
|
of an upper entrance is fairly certain. Prospecting on the hillock
|
|
|
|
|
above the entrance didn't yield results. It concerns there of an
|
|
|
|
|
objective to see again because the vegetation and the snakes didn't
|
|
|
|
|
permit us to operate an efficient search pattern.</p>
|
|
|
|
|
<p>The junction with this higher entrance must be at the level of
|
|
|
|
|
the Little Green Men's passage; either by the wet chimney at the
|
|
|
|
|
bottom of the 1st fault or in the roof of 2/3, there where the
|
|
|
|
|
draught is lost. For the other part, the presence at the bottom of
|
|
|
|
|
another strong draught, suggests a lower entrance, probably a
|
|
|
|
|
fossil resurgence. Nevertheless these are only suppositions, the
|
|
|
|
|
caprices of a draught are very difficult to deal with.</p>
|
|
|
|
|
<h3 style="clear: both">Conclusions</h3>
|
|
|
|
|
<p>One sees from this brief analysis of the cave that the chances
|
|
|
|
|
of a continuation aren't minimal. Now this cave isn't extremely
|
|
|
|
|
difficult of access or of exploration. The work [god knows - rotted
|
|
|
|
|
to be there mend] very soon, but it is nevertheless a secondary
|
|
|
|
|
objective compared with other Austrian possibilities.</p>
