There are two Smithsonian Magazine articles — one from a few days ago, one from 2013 — that may be of some interest to my readers.
The older one is about a Russian family of four that fled into the taiga to escape Communist persecution and wound up staying there, completely isolated from the rest of mankind, for 40-odd years. The parents had two additional children during this time period. Some geologists discovered them in the 1970s. Long story short, the mother had died by then, three of the four children died relatively soon after their discovery, the father lived into the 1980s, and the single remaining daughter returned to the taiga. I’m not sure if she is still alive, but she would be 72 now if she is. There is a book about the case.
The other is about how melting glaciers are exposing artifacts and dead bodies which were previously trapped in the ice. Some of the bodies are ancient, hundreds or thousands of years old, but others are relatively recent. One find, for example, dates from 1952.
