Even in holliday break Bartłomiej Pitala and Mariusz Banaszak embarked on couldn't be complete without caving. This time, their destination was Spain and the Fuente Azul cave.
The cave's last exploration took place 15 years ago, in 2011, so the team decided it was high time to push it a bit further.
As usual, the weather wasn't favorable. Heavy rainfall caused the Rio Arlanza to swell, significantly impeding access to the Fuente Azul cave.
Below is a short account of Bartek's exploratory dive:
I managed to navigate the horizontal passage at -135m quickly and efficiently using the Seacraft, reaching the end of the line at -43m with almost no decompression stops. After attaching my reel, I began exploring new sections of the cave.
After traveling about 40m along the passage at a constant depth, I reached a crevice running almost vertically downward. From this point on, the cave has a distinctly Swiss cheese feel – blind depressions and false passages that forced me to backtrack a bit two or three times and choose a different route. Imagine my surprise when, continuing down the crevasse, I reached a depth of over 100 meters, and a passageway stretching there. Unfortunately, it didn't get any easier, as the cave almost immediately began to shallow again with a series of passages and vertical pits.
I also had some trouble stabilizing the handrail, as the cave walls are very smooth, and the formations growing on them are too delicate to be used for stabilization. However, they were perfect for obscuring visibility with the slightest flick of a fin, or even when exposed to gas bubbles released from the rebreather.
After shallowing down another well, heavily overgrown with formations, to a depth of -57 meters, another horizontal passage appeared. However, the distance from home, the complex profile, rapidly deteriorating visibility, and the general "unpleasantness" and narrowness of the passage made me decide to end my exploration and begin my "ascent," or rather, my return journey to -100 -> -43 -> -135 -> 0 meters. The dive lasted 4.5 hours. It's a shame we didn't have another day to calmly, this time on a string, reach the new face and continue a bit further.
In the comments, you'll find a video from the expedition prepared by Bartek.
