Quick Answer
Build a tree-well shelter by digging a trench around the trunk, creating a windbreak and snow wall, and using branches and snow to construct a roof. Keep the entrance narrow and the roof steep. Choose a tree with a large trunk and a stable branch system.
Choosing the Right Tree
When selecting a tree for a tree-well shelter, look for one with a large trunk diameter (at least 2 feet) and a stable branch system. Avoid trees with dead or damaged branches, and those growing near potential hazards like power lines or cliffs. A tree with a wide, flat area around the trunk will provide a more stable foundation for your shelter.
Digging the Shelter
Use a shovel or your hands to dig a trench around the trunk, about 3-4 feet deep and 2-3 feet wide. The trench should be slightly lower than the surrounding snow to prevent water from accumulating. As you dig, create a windbreak by piling snow against the trunk, and use it to construct a snow wall around the shelter.
Building the Roof
Gather branches and logs to create a sturdy roof frame, and lean them against the snow wall. Cover the frame with a layer of snow, and then with branches and leaves. Aim for a steep roof slope (about 45 degrees) to prevent snow accumulation and ensure the roof remains stable.
Final Touches
Use snow to reinforce the walls and roof of your shelter, and create a narrow entrance to conserve heat. If possible, add a bed of snow or pine needles to insulate the floor. Monitor the weather and be prepared to reinforce your shelter if necessary.
