A couple who were members of my outdoor club many moons ago did their honeymoon by paddling an 18’ canoe, self-supported, over 1000 miles in the Canadian Northwest (the Mackenzie River, if I recall correctly). When they had their first child a couple of years later, they took the babe, at the tender age of 6 months, on a similar trip on the Yukon. Both were schoolteachers as well as skilled outdoors-folk and they would spend every summer off on such trips. Instead of having to scrabble for “survival” they had the leisure to seek out and engage the people that they were able to find along the watersheds.
They did some great slide shows at our club meetings after those adventures. Among the fascinating tales they brought back of encounters along the rivers was of an elderly native man with whom they spent several days, helping him prepare fish for rack drying for his winter stores. One evening he told them how among the hunting traditions handed down for generations through his family was one for preparing to stalk and kill mammoths (in case they ever returned)! Since it is now thought that mammoths may have survived in remote regions of the High Arctic as recently as 6,000 years ago, it is not irrational to think that such oral traditions might have survived.
Personally, I dislike those contrived “survivor” set-ups and would rather watch a documentary showing experienced and well-equipped folks doing a low impact trip into a wilderness regions. The phony “crises” that are built into those “survivor” shows annoy the hell out of me. And the things that the people involved “have” to do for food and shelter are often environmentally destructive. Plus such shows have the effect of convincing clueless jerks that they should stumble into the wilderness with a bowie knife, a tarp and a lighter, wreaking havoc with their browse bed “shelters” and fish-guts, smoldering campfire and turd field leave-behinds.
