Results of January Expedition to Abysso Led Zeppelin
A return visit this past January netted the joint Hungarian-Italian team an additional 2 kilometers (1.24 miles) of horizontal passage in the Abysso Led Zeppelin, a cave in the Canin mountains.
The new gallery starts at a depth of around -950 meters (-3,117 feet) and ends up getting close to the surface on the side of the mountain. It is suspected that long ago it would have been the main water outlet for the cave, since then tectonic movement under the Canin mountains has caused a new lower drain to appear.
Explored by Italian cavers in the 1990’s to a depth of -960 meters (-3,248 feet), the effort was renewed in 2008 after water tracing results signaled a connection between the cave at 2130 meters (6,988 feet) above sea level, and the Gliun spring at 460 meters (1,509 feet) above sea level, indicating a potential depth of the cave of 1600 meters (5,249 feet).
A visit last march discovered 1.5 kilometers (0.9 miles) of new passages in the deepest recesses of the cave, extending the total depth to -1030 meters (3,379 feet).
