Quick Answer
When choosing between a tree well and other shelter types, consider the wind direction, accessibility, and the tree's health and stability. A tree well provides better wind protection and is easier to dig than a snow trench shelter. However, it may not be as effective in extremely cold temperatures.
Assessing the Tree Well Site
When selecting a tree well site, look for a coniferous tree with a trunk diameter of at least 6-8 inches and a relatively flat area around the base. The tree should be sturdy enough to support the weight of snow, but not so large that it creates a wind tunnel effect. Avoid areas with standing water or where the tree’s roots are exposed, as these can compromise the tree’s stability.
Digging the Tree Well
To dig a tree well, start by scooping out a shallow pit around the base of the tree, just deep enough to clear the snow. Use a shovel or a snow saw to remove the snow, working your way around the tree in a circular motion. The pit should be about 6-8 feet in diameter and 2-3 feet deep. Add a layer of snow or leaves to the pit to create a windbreak and help retain body heat.
Winterizing the Tree Well
To make the tree well more comfortable, add additional features such as a windbreak or a snow wall to block cold winds. You can also create a bed of dry leaves or pine needles to insulate the area and provide a comfortable surface to sit or lie on. Finally, use a space blanket or a emergency bivvy sack to stay warm, and try to stay dry by changing into dry clothes if possible.
