<p>The <acronym>GSAB</acronym> expedition was organised from 5th to
29th August, 1977</p>
<p>Several individuals from different clubs joined up, and in
parallel with the exploration of the <span lang="fr" xml:lang=
"fr">Gouffre Ovni</span> (-565m), the <acronym>GSAB</acronym>
expedition deepened <span lang="de" xml:lang=
"de">Ahnenschacht</span> and cleared up some unknowns.</p>
<ul>
<li><span lang="de" xml:lang="de">Frigoschacht</span> (alt 1875m)
was connected at a depth of 130m via pitches of 17, 5, 9, 9, 5 and
18m, with a final 11m pitch into <span lang="de" xml:lang=
"de">Ahnenschacht</span>.</li>
<li>The Vegetable Garden was surveyed</li>
<li>The Yodl system was explored, pushing <span lang="de" xml:lang=
"de">Ahnenschacht</span>'s depth to 607m</li>
<li>The <acronym>KGB</acronym> system was explored.</li>
</ul>
<h3>Yodl system</h3>
<p>From the entrance, after 70m down the <span lang="de" xml:lang=
"de">Josef schacht</span>, climb down 7m over a large block and
descend about 12m in the bottom of a meander. Progress is then in
the meander, with a short climb in a fault on the left and a 120m
pitch, in sections of 22m and 100m. Beyond is a tight canyon with a
20m pitch to a sump at -607m (the last part of the 100m pitch is
wet).</p>

<h3>Mini-expedition from 25th June to 5th July (among
individuals)</h3>
<p>The possibility of a connection with <span lang="fr" xml:lang=
"fr">Epag&eacute;dure</span> prompted a number of individual
Belgian cavers to organise a mini-expedition.</p>
<p>We didn't make the connection, since a bed of dolomite
eliminated all hope. However, the trip did allow several Belgian
cavers to discover a new Austrian cave.</p>
<p><b lang="fr" xml:lang="fr">Le Bilan</b> : -500m at first,
several different endings and a new theory for the pursuit of
caves.</p>
<p>-150m in the upstream system from the <span lang="de" xml:lang=
"de">Josef schacht</span> : stopped by something and fissure (a
high and tight canyon).</p>
<p>A new look at some areas: Enigmatic, <acronym>KGB</acronym>,
<span lang="fr" xml:lang="fr">Gruy&egrave;re</span> and
Schnaps.</p>
<p>A visit and more exploration in the Belgica series.</p>
<p><b>After the Bivouac</b> : a 10m pitch, then turn left into a
small passage, ignore three pitches to the side, then descend
pitches of 8 and 13m to arrive at some easy squeezes on the left.
After this, a climb of 5m and a 42m pitch. Stops in a sand blockage
at -410m.</p>
<p>Over the 13m pitch a small passage goes to several climbs in a
fossil series. There is a 25m pitch and two 10m pitches ending in
several very tight chimneys.</p>
