Quick Answer
To evaluate the safety of a tree well shelter, inspect the tree's condition, assess the snow load, and consider the risk of collapse or avalanches in the surrounding area. Look for signs of decay, dead branches, or structural weaknesses. Also, check the snow depth and consistency to ensure it can support the weight of the shelter.
Inspecting the Tree
When assessing the tree’s condition, look for signs of decay, dead branches, or other structural weaknesses. Check for cracks, splits, or soft spots in the trunk and branches. Evaluate the tree’s height and diameter to determine if it can support the weight of the shelter and any additional snow load. A minimum diameter of 10 inches (25 cm) is recommended for a tree well shelter. Also, check the tree’s lean and orientation to ensure it is not in a weak or unstable position.
Evaluating Snow Load
Assess the snow load around the tree by digging a small pit or using a probe to determine the snow’s depth and consistency. Check for any signs of instability, such as recent slides or cracks. Consider the risk of avalanches in the surrounding area and whether the snow load can support the weight of the shelter. A general rule of thumb is to maintain a safe distance of at least 10 feet (3 meters) between the tree and any potential avalanche terrain.
Additional Safety Considerations
When building a tree well shelter, consider additional safety factors such as wind direction and speed, as well as any nearby hazards like cliffs or steep slopes. Ensure the shelter is built with a stable and secure entrance, and that it is designed to withstand any potential wind loads. Regularly inspect the tree and shelter for any signs of damage or instability, and be prepared to evacuate if necessary.
