2019 It was difficult to assemble the expedition as there was no clear continuation, especially not around the siphon but, when cavers from Moscow and Irkutsk also joined the SGS and ASU team, a group of 15 gathered. The surface camp was set up in a proven location near Lunnaja cave, and a team of four: Evgenij Sakulin, Petr Kovešnikov, Anastasija Janina and Andrej Minogin departed to the bottom, to set a Camp Siphon there and to try to find a continuation in the ascending tributary at -600 m. Yet on the very first day at the bottom Evgenij and Anastasija managed to crawl through a narrow, half flooded passage and reached a meander behind the siphon. The cave continued in the right direction. Other plans were scrapped and the team, reinforced with Evgenij Rybka, Vasilij Samsonov and Vadim Loginov (there was a phone connection from the camp to the surface), set off to the new part. It was a wide meander with a stream at the bottom and 1–5 m deep drops. After a while the stream disappeared below the dripstone floor in a narrow passage, above which the "Big gallery" began. It was dry, the ceiling gradually lowered, the tunnel turned to a crawl, solid floor was replaced by clay, it got wet. This part took 2 hours to cross. The passage was cut by a new meander where, below the ceiling, the "Big Collapse Hall" opened up. The following meander was not wide, with a small stream at the bottom, in places covered with dripstone. Another tributary joined from the left.
