The sections of Lamprechtsofen showing the progress in exploration - the above one from 1975, the lower one from 1997
In 1992 we have also started another stage in the exploration of the massif. Prospecing in the southwestern part of Nebelsbergkar we found another promising cave labelled PL-2. Its entrance lies about 95 m above the Vogelschacht entrance. In 1993 we reached the depth of about 500 m in this cave and we enter a few tens of meters below the bottom into a nearly one kilometer long system of old muddy galleries with a strong draught. They are dissected by numerous otches with streams disappearing into collapses or inaccessible fissures. In 1995, parallel to the exploration in Vogelschacht we try to find an extention toward the north. After trying hard for several days we enter a tight northbound fissure with a strong draught. However, to our utmost surprise, we are moving upstream. Finally we get into a hall with a waterfall from near its roof. So ends our exploration in PL-2. In 1996 we only managed to do some prospection for several days in the cirque, finding more promising entrances. They will be, together with PL-2 to the goal of our expedition this year. The perspectives of the exploration are still looking attractive. Nebelsbergkar rises to about 2400 m in its western part, and the highest entrances are at 2380 m. The area is very poorly investigated, partly covered with perennial snows, rock debris, dissected with hundreds of clefts. However, what we found in PL-2 supports our hopes for finding a continuation of Lampo to the highest parts of the cirque. One must remember, however, that the exploration becomes more and more difficult and tiresome because of the narrowness of the passages and fissures in the caves explored there. The key problem may be crossing of the cirque situated south of Vogelschacht. If this would be done, there would have appeared a chance for a next stage of exploration and an attempt at extending the system as far as the southern order of Nebelsbergkar. This would take many years and a lot of enthusiasm, persistence and consequence on the part of the members of the successive expeditions. It seems worth of it, as there are few places in Europe where the lower entrance of cave lies at the altitude of 664 m.
