deep under the Gr. Tragl - Ozone hole 1625/406
From 04 to 06 October 2007, once again, a research tour in the ozone hole may be carried out. The 51-hour tour took Jeutter Peter and Robert Seebacher, the bivouac was used in 460 m depth as a base for research.
The first day was descended to the bivouac and on a directly behind the onset of horizontal response explored. The relative proximity to the corridors of the sun shaft head makes this cave particularly interesting part. In some cases, only about 70 m missing a few meters vertically and horizontally between the two caves. The attempt to dig a clogged with thick clay continued failed. Similarly, the rise in a Seitenkolk provided no useful result. In the third installment but it was further push forward. This was also, unfortunately, soon reached an insurmountable climb, with no drill. Strong weather management make this approach but to hope for a possible connection. On the second it went
Research Day in the deepest parts of the cave so far. The past is already in the Tour discovered Bach poured this time even more (~ 20-30 l / s) and so we gave up a descent into the end manhole at -591 m. Instead, we
went out at the big -570 m in the NW migratory path to explore further.
To our horror, ended the beautiful tunnel after about 50 m in a Lehmverschluss or two siphons, from which the stream emerges. We succeeded, but fortunately an over 8 m high chimney in an upper floor to penetrate. Here dominate beautiful phreatic profiles and initially dry clay soil. Soon, however, changes the character of the corridor. It's always about 20 degrees of tilt up, is being formed in the sole passage a canyon. Everything is with slippery mud covered and there are hardly any useful handles or kicks. So we fought our way to a straight line, about 80 m long passage up, we gave the name " impassable path" . Measurement trains with up to 26 m in length but are compensated for the effort. At a bend in the direction SW seemed the course to be enjoyable again. Sorry, but followed after a few meters, a clay pit beam and a 4-foot ascent. Here, then went to our last piece of rope to the end and the same subsequent 5 m descent had to overcome and climb and safety loops. Another climb, could be circumvented through a bottom hole, so we came back into a higher gear. Re cord pulls straight from here a beautiful passage on the summit of the Gr. Tragl inside. On the ground thundered in a deep canyon in the "Traglbach. The corridor finally opens into a transverse gap, the water from the direction of NO from a narrow gap emerges. In SW direction to the gap is large and continues until one was unable to over 10 m high climbing, shall be implemented. Due to the lateness of the hour and was due to lack of material for us here this time final. The section "impassable path - Traglbach" overcomes a horizontal extent of more than ¼ miles and an altitude difference of + 100 m The end point is reached already far below the size. Tragl (2179 m), only about 200 m SE of the summit. Thus it is the first time we succeeded in this area under the peaks of the chain-Löckenkogel Tragl-train to arrive. Open sequels and clear weather can lead to further discoveries in this area hope. A total of 440 m measured
new ground, resulting in the ozone hole for a new total length of 2,345 meters. The depth of -591 m remained unchanged for the time being (Robert Seebacher, 10.2007).
