Franco was the guide, and we were joined by Ursula and Lutker, from Germany. It's a live cave, at least in portions, with water still infiltrating.
The cave is reached by rappelling down about 7 meters, through a smallish entrance. It has been explored and toured for a long time, so there are smoke scorch marks, and some "clean up" of the floor and broken stalactites and stalagmites. There were a few fixed ropes in the cave, but no technical climbing. There were some very pretty and interesting features, including a near-column that had spread at different water levels, with minature stalagmites inside, and an area where all the stalagmites were bent significantly off vertical, due to significant airflow over many centuries.

The large images are good for seeing fine detail, and for printing. If they are larger than 3000 pixels in any dimension, they are shown at 1/2 size; the original full image is available on request for those. Movies are MPEG4 movies (new ones are H.264), and the thumbnail gives the size of the movie.

Beautiful column with two "plates" formed when water was high for long periods at two different levels.
Lutker took this movie of me climbing out the entrance. It starts when I got on the ladder, so I'm not visible until about 1 minute 20 seconds.
Lutker took this picture (left to right) of me, Ursula, and Franco, before we hiked back to the car. The view is looking west down the valley.
