When I lived in Ottawa in the 1970s I was a scoutmaster. One of the important skills we taught the boys was winter survival. Ottawa winters are very cold and snowy, so each year we held a winter survival course over a long weekend in Gatineau Park, a wilderness reserve across the river from Ottawa in Quebec; no amenities or facilities there in those days. The course included, among other things, snowshoeing, orienteering, how to dress for extreme cold, building a fire and cooking meals in the cold, building a shelter for sleeping and actually sleeping two nights in it, maintaining bodily hygiene, first aid, etc. All the gear would be carried into the bush by the boys on sleds they built and pulled; all of us wore snowshoes because the snow was very deep. We all had a lot of fun and learnt a lot, especially the importance of being prepared and properly equipped for extreme cold. I should point out that the best time to do this was when the temperature was well below freezing as the snow was “dry” and didn’t melt on your clothing or gear.
