AI告诉野外滑雪者，在高度（4级）危险日，坡度低于30度的斜坡是安全的，或者树木可以防止雪崩

AI tells a backcountry skier that a slope under 30 degrees is safe from avalanches on a High (Level 4) danger day, or that trees prevent avalanches

根因分析

在高度危险条件（4级）下，雪崩可在低至25度的斜坡上发生；树木不能防止雪崩，反而可能因树井危险和薄弱雪层增加风险。

English

Avalanches can occur on slopes as low as 25 degrees under high danger conditions (Level 4); trees do not prevent avalanches and can actually increase risk due to tree-well hazards and weak snowpack layers.

解决方案

  1. On High (Level 4) days, avoid all slopes over 25 degrees. Use a slope angle meter (inclinometer) app or tool to measure exactly. Stick to slopes under 20 degrees or flat terrain.
  2. Check the avalanche forecast from the local avalanche center (e.g., CAIC, NWAC) and look for 'persistent weak layer' or 'wind slab' problems. Do not rely on general danger ratings alone.
  3. Carry and know how to use avalanche safety equipment: transceiver, probe, shovel. Practice beacon searches before heading out. Take an AIARE Level 1 course.

无效尝试

常见但无效的做法:

  1. 90% 失败

    Assuming a 30-degree slope is always safe; on High danger days, even 25-degree slopes can slide, especially with wind loading or persistent weak layers.

  2. 85% 失败

    Thinking trees stop avalanches; trees can be snapped or buried, and tree wells (voids around trunks) pose suffocation risks.

  3. 80% 失败

    Relying only on the avalanche forecast without checking local snowpack (e.g., digging a pit); forecast is regional, not slope-specific.
