Montanero, I highly recommend the book
'Lost in the Wild' by Cary Griffith for your project. It is a very detailed parallel account of two unrelated incidents in the Boundary Waters area near Canada.
Story 1: A Scout group's very experienced guide steps into the bush alone with no gear looking for a canoe portage, gets lost, and disappears for days. The two adult Scout leaders have to carry on and extract their young charges from the wilderness then initiate a search.
Story 2: An inexperienced solo hiker gets lost after veering off of the
Pow Wow Trail and through futher blunders finds himself separated from almost all his gear.
The book is quite well written plus it includes photos and maps from each incident, both of which are very relevant to
this ETS discussion.
A
short account including these stories is on the Minnesota DNR site.
