Winter Survival Tip: Hole Up in a Tree Well

Snow is not necessarily an enemy in a blizzard. It's a great insulator, and if you build a proper snow shelter, it'll keep you safe and warm for a short period.

You can quickly make an effective snow shelter in a tree well (the depression in snow around a tree trunk formed by the protective canopy of branches above it). First, reinforce the natural enclosure by propping up additional branches around the lowest branches. Next, dig out the snow accumulated around the trunk. Finally, lay evergreen boughs on the floor to make a comfortable sleeping place that can be as much as 40º F (22º C) warmer than the temperature outside. Survive any wilderness situation with these critical tips.
