We did a full trip earlier today and the system is about 510 meters total however its a backbreaker so it took us a bit over an hour to get around all 3 branches of it. From the waterfall entrance there are 4 smaller rooms along the way until you get to the main room. In the main room you can either follow the flow of the water down a 70 meter stretch to a holding pool or go up another path without any water flow. The holding pool was pretty tricky to get across, luckily there were ladders on the side that I climbed up originally to take a piss but then realized it was an awesome spot to take a photo (this is photo 1). after this room it was a short crawl to the ice room where we found a huge 2 meter tall icicle. This route ended with the tunnel becoming halfway submerged in water and ending with a locked grate.
We crawled back to the main room and decided to check out the other tunnel with no water flow. This path took us to a big room with a good 15 foot ladder, unfortunately it was retardedly full of spiders. When we looked down the next tunnel we saw an exit that gave us false hope of an alternate exit and just turned out to be another grate.
