research tour in Almberg Cave System (1624/018)

From 6 to 10.06.2007 again, a major research tour during the Almberg cave system.
goal was to continue the survey work in the upper branch of the Almberg ice and stalactite cave that were there started about 4 weeks from us.
Since the beginning we in search of the two compounds with the snow cone cavity of pages Almberg the ice and stalactite cave we had discovered a year ago in the snow cones cave. Various descriptions of manholes in old records but led us to, not from the snow cone cavity through the Almberg- Ice and stalactite cave to the outside, but on the contrary, measured from the entrance to the direction of women in snow cone cavity. In the last tour turned out that the requested connection between Panama Canal and Broadway is not possible since both are in different parts of the cave floors with 100m height difference. Our survey, however, led us up to about 200m, 50m and higher, closer to the second link on Scherbensiphon. So we decided on this tour, but now find the connection to address the part of the snow cone cave, because you can save about 3 hours thereby advancing the Almberg ice and stalactite cave.
But it ultimately quite different: in the unknown parts of us Almberg ice and stalactite cave that start behind the Scherbensiphon the snow cone cave come, we move it quickly, but instead of upwards, towards Broadway, spacious cave passages lead us deeper and deeper down. Finally, we come out in a striking hall with stream, we can use the old, inaccurate sketch plan clearly identified as a hall of the Rio Negro. The Rio Negro is likely, however, in this area do not be! He is in the plan, in the western branch of the Almberg ice and stalactite cave. Only about 200m further we eventually find even "our" Panama Canal and to the second connection between Almberg ice and snow cone cave and cave. The Sensation is perfect. In three days we create through our surveying a 700m long Rundzug, the now a grueling trail in the heart of the cave system formed. Broadway and thus our measurement of the last tour we do not reach from here. Since this part, however, about 100m above it and has many large bays, all of which are not run, there remains the possibility of ring closure by the Broadway.
were on the edge from up to 14 hours, 5 day trips also stations for a permanent Eismonitoring installed. The purpose of this equipment is the detection of volume changes, and movements within the large Masseneisvorkommen in the snow cones cave.
Conclusion: Extremely strenuous tour in a fascinating caves, 72 lightless hours and many successes, thanks to a perfect team, are behind us. The study of Almberg cave system is a significant step forward. (Thomas-Michael Schneider, 6.2007)
