3 days caving in 217 which is probably the hardest caving I have done in my life. It had an entrance series akin to New Henslers which starts after 70m of absailing, maybe two of them. This was then followed by 200m of pitches, before finally reaching camp. At that point I got ill and threw up, but managed to finish the days exploration.
I spent most of the second day at camp and being ill, before dropping down large pitch (50m~) near camp to room full of mud formations
We then went back out but only took the lightest bags with us. It was cold and wet and the sun rarely ever shined when I was outdoors. Not an expo I would care to repeat, I find more bloody cave in Matienzo. The only real discovery was on the last day as usual when I spotted a high level passage that kept going.
