Quick Answer
To detect tree wells when hiking in deep snow, look for areas with deep drifts and uneven terrain, and check the snow around trees for a sudden drop-off or a circular pattern of disturbed snow. Use trekking poles to probe the snow, and be aware of your surroundings, especially on slopes. Consider using a probe or a long stick to check for snow depth.
Understanding Tree Wells
Tree wells are deep holes of packed snow that can be formed around the base of a tree when the snow is deep and has been disturbed by the wind or human activity. These wells can be difficult to spot, especially when the surrounding snow is deep and uniform. They can be a significant hazard, especially for hikers who are not aware of their presence.
Detecting Tree Wells
When hiking in deep snow, it’s essential to be aware of your surroundings and to check the snow around trees for signs of a tree well. Use trekking poles to probe the snow, especially on slopes, and look for areas with deep drifts and uneven terrain. When you suspect a tree well, use a probe or a long stick to check the depth of the snow. If the probe or stick goes in more than a few feet without hitting the ground, it’s likely a tree well. Be cautious and consider taking a different route if you suspect a tree well is present.
Safety Precautions
If you encounter a tree well, be cautious and consider taking a different route if possible. If you must cross the area, use extreme caution and consider using a rope or other safety equipment to secure yourself. When crossing a slope with deep snow, use a “snow anchor” technique, where you plant a trekking pole or probe in the snow and use it to stabilize yourself. This can help prevent a fall into a tree well.
