<underground_description>Few details available, since we were for many years unable to obtain a survey. A figure of over 6 km long in 1987 was quoted, but this would appear to include the <ahref="40.htm">Eishöhle</a>. Contact was finally made with the French group in 1997 and <spanlang="fr">Denis Motte</span> has sent us a plan on 12 A3 sheets, dated April 1995, which gives the length as 1885m. The following description is made up entirely by looking at the survey, and should not be taken as reliable. It is hoped that we will do better after visiting the cave with a view to finding its connections with <spanlang="de">Stellerweghöhle</span> (<ahref="../../1623/41.htm">1623/41</a>) and <ahref="../../1623/144.htm">1623/144</a>.</p><p>Open shaft descends 5m to first rigging bolt, then short pitch to snow plug. The way out is to the NE, where the survey shows a couple of (inaccessible ?) question marks and a traverse over a pit. Narrow rift continues past another unexplored small passage to the right, and in 20m opens out into a sizeable chamber. The boulder floor drops away to the north (left) and ahead. Up right is a bouldery antechamber with the base of a ramp up SE. A short passage here chokes.</p><p>20m across the boulder slope, it is possible to descend the slope left into the main part of <blang="de">Oberpfälzer Halle</b>, 15m wide and 30m long, now heading west, still descending over boulders. To the right is a 15m rift passage with an inlet. Ahead, the chamber narrows, but large bouldery passage continues with two or three big boulders (over 5m). To SW is a junction marking the start of <blang="de">Jsartal</b>. Up a steep ramp to the right (NW) is unexplored, whilst left, south, goes directly below the entrance in a passage with a slot in the floor. After 25m is a widening and junction. Right curves round to end below an aven. Left goes quickly to another junction. Right soon chokes in boulders, whilst left ends quickly in an undescended rift pitch.</p><p>Back at the junction at the start of <spanlang="de">Jsartal,</span> the main way SW soon traverses a large hole in the floor, then continues as a small canyon until 50m from the start is a junction in small passage. Right pops out immediately into the side of a ramp rising right (north) to a choke. Down ends in a pitch, which is best reached by the small passage left at the junction. This quickly doglegs and comes out over the pitch on the opposite side from the ramp. The pitch (undescended) is seen to be a widening in a deep floor canyon, which continues as <spanlang="de">Jsartal</span> develops into an 8m wide rocky chamber through which the floor trench meanders.</p><p>After a short way, the trench abruptly ends, and a ramp up above it leads to a junction. Left continues up ramp, but not very far. Right traverses the ramp (another down-section soon ends), then heads west past another blind passage on the right, to break out into a larger passage ahead. Left (south) is the way to <spanlang="de">Geburtstagsgang,</span> whilst right (north) eventually leads to the <ahref="#fsw"><spanlang="de">SchwarzmooskogelEishöhle</span> connection</a>.</p><h4lang="de">Geburtstagsgang</h4><p>Ascending a low ramp leads past various short side-extensions to <blang="de">Schafott</b> - apparently a breakthrough point in 1986 ? Beyond this, small passage continues SW, with a mudbank on the left, for almost 50m until it widens out and descends a steep slope towards a floor trench. Left here a further ramp ascends east to a choke. The floor trench continues W, then NW, but would seem to be too narrow. Staying on the north side of the trench and heading NW (right from the point of entry) leads through mud and/or shingle deposits in a small zig-zag passage which meets first a small canyon which doesn't go, and then a T-junction over another canyon.</p><p>Right ends after ten metres or so, whilst left (west) meets another junction where a further trench comes in from the left (south). This also appears to be too small to follow, but would seem likely to
