I recently watched a series of Les Stroud’s videos called “Stranded in Winter” . I think this is from his pilot season before the Discovery Channel officially called them the “Survivorman” series. Les is dropped off in Wabakimi Park with minimal gear and 1 energy bar per day. He experiences temperatures of -20 to -41C. He has no sleeping bag or shelter. He makes an under-spruce-tree shelter and discusses pros and cons of various emergency shelters. He shows the reality of how thick the southern boreal forest really is, with its abundance of blow down and annoyingly thick undergrowth. Great comments too on what the books say vs. the reality.
