In the 1970s, Belgian cavers found vast horizontal passages amounting to about 5km in total – and a continuation to -602m. Their pushes came to an abrupt halt, however, when in 1975 a caver fractured his pelvis and had to be transported out of the cave. It was Austria's biggest cave rescue operation in the 20th century.</p><p>Since documentation of the Belgian finds was fragmentary and of very poor quality, some members of the <span lang="de">Verein für Höhlenkunde in Oberösterreich</span> decided to fill in the gaps in the maps and resume surveying activities.

<underground_description></p><h4>Entrance series</h4><p>The entrance is in a small shakehole situated on the ridge separating <span lang="de">Feuertal</span> and <span lang="de">Hintergras.</span> The cave starts with four pitches (p14, p11, p5 and p11) which drop onto a slope formed of big boulders (rope desirable). After this, another series of small pitches (p9, p7, p6, p4, p10, p18, p11) from which is reached the <span lang="de">Sinterterrasse</span> at -141m.</p><p>From this point, one has left the zone of small pitches and started a series of pitches which in reality are part of a single shaft down to -400m.</p><p>Indeed, if you had an unfortunate accident on the <span lang="de">Sinterterrasse,</span> you would fall all the way to -400m. These pitches are usually wet, especially after rain... Here is the list of pitches: p25, <span lang="de">Schuppenstufe</span> 30, p10, <span lang="de">Sicherungsstufe</span> 32, <span lang="de">Schachtgabel</span> 48, a 10m ramp, <span lang="de">Josef Schacht</span> 100m. On the <span lang="de">Josef Schacht,</span> a pendulum 6m from the top enables one to reach the entry to the Horizontal network. Descending the <span lang="de">Josef Schacht</span> a little further, after a 6.5m and a 10m pitch, access can be gained to a wide canyon, active in the bottom, and which ends in a fissure. This canyon is fossil in the upper level and certainly presents possibilities for continuation.</p><h4>Lateral development from <span lang="de">Josef Schacht</span></h4><p>After one has crossed the "doorway" and a short squeeze, one enters the network proper. At this point is a passage covered in rather special formations. The first junction gives access to a network ... [unfortunately there are lines missing in my photocopy of <span lang="fr">Spéalp</span> 1]</p><h4>The Vegetable Garden</h4><p>This fossil system, which has not been fully travelled through, contains numerous possibilities. It is reached by three principal access routes: the pitch already mentioned; a descending fissure a little before the Belgica; and a sloping passage with formations in the Mammoth pitch chamber. The system is composed of a big chamber with numerous passages and junctions; it is very poorly known and no doubt houses many surprises. Continuing along the passage, one passes a step of 4m to find a junction, to the left at which lies the bivouac.</p><h4>Belgica system</h4><p>Directly after the bivouac, there is a 10m pitch, and at the bottom, a new junction: downhill the Belgica passage, of fairly small dimensions, which leads, after traversing past three holes, to a descent of an 8m and a 17m pitch and to the squeezes passed by our French colleagues.</p><p>Uphill, discovered by D.Motte and PIE, in the course of the expedition in 1974, is the <span lang="fr">Galerie de Francs Comtois.</span> This is a large ascending fossil passage interspersed with traverses, dips and pitches. It reascends to -90m. At -150m, a 20m pitch reaches the <span lang="fr">Résomega.</span></p><p>A little before the 20m pitch, a short descending canyon passage avoids the 20m pitch and the series of squeezes following it. The <span lang="fr">Résomega</span> is an alternately ascending and descending passage, very chaotic, interspersed with several junctions and pitches which leads to the <span lang="fr">Balcon du Visionnaire,</span> offering several possibilities. A 60m pitch gives onto another 60m pitch which is undescended. There is another big pitch in excess of 100m and an unfinished ascending passage. A little before, a 10m pitch allows one to reach a passage interspersed with 3 junctions and 7 exits ! This shows the level of complexity which we ran into.</p><p>It was also at the <span lang="fr">Balcon du Visionnaire</span> that an accident occurred in 1975, which terminated exploration in that year.</p><p>Back in the Horizontal network, and after passing a little bouldery climb an inlet is encountered, named The Bath. The passage continues a little longer, to end in a pitch. [ exploration incomplete ]</p><p>The
