"construction site" deep in the mountain again brings breakthrough in large open sequels. South wall cavity (1543/28) is now the third longest cave in the roof stone.
Between 08th to 11 February 2007 took Tenreiter Clemens, Gerhard Wimmer and I (Robert Seebacher) a successful, 71-hour research and survey tour of the Dachstein hole.
Already on the first day of the long march was to been tagfernsten bivouac, the covered tube hum bivouac. Due to the relatively mild this time of this day's destination was grinding bags quickly reached and it could be measured on the same day or 158 m. About a nondescript bottom hole that recognizes a few meters behind the bivouac, were able to penetrate into an unknown path and close a Rundzug to the Lower ripple tubes.
On 2 days we went in only a month ago discovered cave part Nirvana, by a much bewetterten gravel closure refers to a sudden end. Overcoming this obstacle was the main objective of this research cruise. First had to be dug about 3 m wide down. There it was then after about 1 hour is possible to push with the feet of gravel into a small-scale sequel. A close Schluf brought us, finally after about 2 hours work grave in a small chamber. Here it was initially not even possible to turn around. Only after a little clearance, it was with sorrow and distress, business, and the study is now pointing upwards in continuation. The disillusionment was great to see just another gravel cap was. Actually, the action would now have to be canceled with no prospect of a successful way through, since there was no possibility to store the "overburden" of a further excavation.
We shot but to persevere and create the material means of slip-rope-bag method from the conclusion. This required the bag from me lying in the Chamber of Secrets in be filled. He was then pulled through the narrow Schluf by Clemens and Gerhard on the outside, taking in about every 2 Load at a narrow and become wedged by repeatedly solved strutting down and had to. In this complex and hard work we had always suspected the "grand continuation of the corridor in the mind's eye. Otherwise we would not have done well. However, we thought
several times about giving up when, after the removal of the gravel is only opened a gap of a few cm. The weather management increased during the clearing but steadily, and finally succeeded after a further 6 hours, the chicane to overcome. A large, soft sand and gravel-covered tunnel opened before me.
did a quick recce and a satisfied look into the dark the next disappointment. Through the back and strutting of the bag The conclusion was again moved so that it was impossible for me to return to his comrades. Only after a further hour Buddelei it was finally made. The way to a new territory was finally open. A total of 9 hours had we stayed here, but we were happier with this completed "construction site" almost 1300 m below the Gosau glacier.
Behind the 9-hour Schluf is now the cave as a "wind gap Gang with a diameter of 5-7 m further towards the center point continued. be overcome after about 150 m had two climbing points of 4 and 9 meters. Then, the transition leads to a steep slope of about 30 ° up. Two other climbers customizable 4m steps lead finally to 316 m to 25 m high chimney, without the drill could not be defeated. This vent, and an approximately 100 m above the cave ceiling begin gait are promising approaches for further research. To achieve this endpoint must away from the entrance, are now already covered about 4.5 km distance.
On the third day it was a bottleneck at time low point of the cavity to expand, and to overcome . A few meters behind the cave widens to approximately 1.5-2 meter tube, which leads further into the depths. The course could be followed to a length of 129 m, where vice versa in a bewetterten bottleneck was. This point is already 492 m below the entrance and is the lowest point so far reached the southern wall cavity dar. An advancement seems possible here.
Overall the tour provided an increase in length of 603 m, which results in the south wall cavity, a new survey as of 9351 meters.
The level difference is increased to + - 509 m (+17, -492 m).
