left the cave to Perovo-speleo to develop it further. They made 5 expeditions into it. On the second expedition they dug through a narrow meander, bypassed the siphon and reached the depth of 1,000 m. Further expeditions brought the depth of 1,250 m where an underground creek flows into a siphon. For the work in Moskovskaja cave the team, led by Demidov, was awarded the A. Morozov medal for 2011, the highest Russian award for achievements in speleology. Further expeditions, the last in 2015, discovered several side branches of the cave but none past the terminal siphon. As the team returned to Abkhazian coast in August 2015, to Gagra, they met Aleksej Baraškov, the new president of Perovo caving club, where the team's caving career began. They were also exploring Verëvkina and in 2009 while they traveled to the cave from Gagra, on a track high in the mountain the jeep, a GAZ-66 capsized and two explorers were injured, one badly. So Perovo speleoclub discontinued explorations in Verëvkina, until 2012. In 2013 they broke through a narrow passage at the new bottom (where Perovo-speleo stopped in 2010), at −340 m, and reached a junction of two meanders. One had a strong draft, the other had flowing water (Narnia branch). They followed the water and lost two years in that branch, it was all very narrow. In 2015 they decided to try the meander with draft and with little digging they reached another shaft, at an estimated depth of 360 m, where they stopped because of lack of rope and time. As the cave was developed by both clubs Perovo-speleo, led by Demidov, decided to proceed at that point. In the winter 2015/2016 the access was too difficult so the next, very small expedition took place in June 2016. At the bottom of the last, 30 m shaft, Evgenij Kuzmin discovered a continuation, Babatunda, the biggest hall in the cave, 155 m deep. They reached the depth of 630 m. In August 2016 a joint expedition of both teams followed and reached the depth of −1000 m, with an open continuation. During the October/November 2016 expedition of the two teams the cave was deepened to 1350 m, but snow surprised the cavers on exit, roads were impassable, all-road truck could not come and they walked 3 days in the snow to reach the valley. Next expedition in February 2017 used a
