On January 29th, 2013, the Smithsonian Magazine published an amazing story about an Old Believer family living without human contact for over 40 years.
In 1936, after his brother was murdered by communists, Karp Lykov fled with his wife and two children to a narrow, forested mountain valley in Siberia, 100 miles from Mongolia, and 150 miles from the nearest settlement.
At first they were a family of four, then two more children were born in the wilderness. It was a very difficult existence. In the particularly difficult year of 1961, a snowfall in June killed almost everything in their garden. Karpís wife, Akulina died of starvation that year so that her children would survive. Five of the family still survived by the time their homestead was discovered by a geologic expedition in 1978.
They had no firearms or even bows. They had to rely on traps or running animals to exhaustion. One of the sons as a young man, developed amazing endurance and skill as a woodsman. He would go out for several days in winter sometimes bringing home an elk for the family.
They had no salt, and no ability to replace metal cookware which had worn or rusted out. They went barefoot or wore birch bark footwear. Their cabin was a very modest structure with a single tiny window. Nevertheless, they were very resourceful in making do with what they had or could create.
Apparently, one of the daughters, the last surviving member of the family, still lives there to this day.
