Researcher Maya Bykova twice observed Mecheny outside a remote hunting cabin. She had traveled to the area after meeting a young Mansi man whose family had regularly encountered a large wildman near their hunting lodge since the 1940s. In the first encounter on August 16, 1987, Mecheny knocked on the cabin window at early dawn. Bykova and the family rushed outside and saw a figure more than 6 feet tall leaning against a dead tree. After about a minute of looking back at Bykova, Mecheny departed when the dog came out barking. In mid-October 1987, the dog disappeared and was found the next morning, its skull crushed and body ripped apart.
Bykova’s second encounter took place outside the cabin on the night of August 22, 1988, when she and the Mansi hunter watched Mecheny for seventy-five minutes in the woods, where it was apparently looking for frogs or mice. The next morning, they found trampled grass and narrow trails where the creature had walked.
Mecheny is similar to Old Yellow Top, another Marked Hominid primarily seen in Ontario, Canada.
