In the north-west corner of the chamber was a shallow pit poluoplyv Shai, stretched from the north-west to south-east. When it cleared, it appeared that it continues and goes under the wall of the chamber, and then goes out. With further excavation of the pit at a depth of 1.6 m from the floor chamber collapsed, opened the catacombs of the mound. Kata combos dug in the bedrock and consist of a main course and the sending side branches. The main course begins with a north western embankment floors, is on the south-east and at a depth of about 2 m flies the tomb. From him in different directions departs seven lateral moves, two of them Western, half-filled with earth, and one - the north-east - large rounded stone. Code of semi-circular strokes, the height from 1.1 to 1.68 m, width of 75-80 cm in many places on the walls there are small ledges with traces of soot on the one hundred yavshih are fat lamps, covering the diggers at work in the cave.
The total length of main course with side Answer vleniyamii - 55 m clearing blockages of lateral branches, walls and floors of underground tunnels did not produce any material, so that remains a mystery destination catacombs Besshatyr mounds. But the excavation ki shed additional light on another question related to whether the underground tunnels of ca mime mound, or manholes are left by the robbers.
When clearing the main course, which begins at the northern mound floors, from the place where was listed depressions, found the logs to torymi was decorated cave entrance. Log in decorations for four vertical wooden locally dug column, standing in pairs along the walls. They were cross-rungs of the timbers, which were placed in the meridional direction three logs forming the entrance floor. At the entrance there was a flat stone that served as a stepping stone. That Thus, it was found that the underground passages connected with the burial of Rita scarlet, and are a structural feature Besshatyr skih mounds.
Such as the catacombs, but larger were open, as already mentioned, and the Third Besshatyr excavation of the mound.
