Survival in these conditions is a lot of work, require perseverance, training, and real survival skills I have had the privilege of teaching survival four times North-West of Wollaston Lake. This area is very remote and the best you can do for firewood is searching the forest for dead seasoned Jack Pine. Resource are very scarce in this forest and trees are far apart. This is a picture from my last trip up their to teach a course in early April. Note the distance between trees and the small diameter of the trees. Please note this was my chosen area to teach in, i.e. the best forest I could find on high ground in the area after 4 trips to the area. This lush of a forest would be something you would never find near the shore of a lake.
The search for a nights wood in these conditions often takes participants 4 hours, even with 2 people per Fire and its often means walking 500m for wood. I actually took this photo as I was wandering the forest looking for wood for my fire for that night.
