It's all here.
'In the evening, after a hearty dinner, during which we finished almost a bucket of elk meat bought from the Mansi, we sit for a long time by the "potbelly stove" and talk with Alexander Prokopyevich. We settled around him on the skins laid on the floor, and he sat on a block and loaded cartridges. We asked the owner about the signs that we encountered in the taiga on the trees. When a Mansi hunter kills an animal, he goes out on the trail and makes a notch on a tree in a conspicuous place in joy and in memory of his success. First, he-carves out the figure of the animal. Animals have their own conventional notches (see Fig. 6). Notches are made above the figure of the animal. Notches are also made under the figure of the animal, The upper notches indicate the number of hunters participating in the hunt. The lower notches indicate the number of dogs, in the middle of the notch. the Mansi puts their family sign, katpos (see Fig. 7). Sometimes there are several notches at the top of the notch, but only one family sign. This means that the father and his sons were hunting. Until they start their own family, the sons put their father's katpos. The katpos is usually first cut out with an axe and then blackened with coal. There are many such monuments to successful hunting in the taiga.'
In fact , Karelins sports report reads almost like the Dyatlov diaries , missing the train, staying at a school , visiting museums , running out of time,trying a new stove designed by the engineer , holes in the tent from sparks, sewing the tent and socks and boot covers, the explanation of the duty officers, hot and cold parts of the tent that hikers thought too hot , spare skis, how the group reported that sending tourists ahead to make a path and the rest follow taking turns, the set up of a tent and the flooring , it's all in the report. It's like the Dyatlov group with out the sad ending???
I never read it in detail before but it's quite uncanny. Fig 6 and fig 7 show the same wood sign as Zinas( it represents an elk) and the same family names on the trees and as in the diary ,and the statement signed in Mansi .
