Why does Kolevatov have two skis when they found his body?
These are not Kolevatov's skis.
When the 4 bodies were extracted from snow pile in the ravine, they were put into inner parts of the Search party's sleeping bags. Then the bodies were put on self-made sledges. Search party's skis were used to build those sledges. So, on the photo you see the sledge that was used to transport Kolevatov's body from the ravine to the helicopter pad on the Pass.
