Quick Answer
Survivors can return to the same area, but it's crucial to assess the risks and make an informed decision based on the avalanche's characteristics and the terrain. This involves evaluating factors like the avalanche type, debris distribution, and potential new slide zones.
Assessing the Avalanche Area
When deciding whether to return to the same area, it’s essential to assess the avalanche’s characteristics. If it was a powder snow slide or a slide with a small amount of debris, the risk of a secondary slide is lower. However, if it was a wet snow slide or a slide with a large amount of debris, the risk of a new slide is higher. Look for signs like recent avalanche activity, unstable snowpack, and signs of recent loading (e.g., new snow or wind).
Evaluating Terrain and Debris
Evaluate the terrain and debris distribution to determine the risk of a secondary slide. If the debris is widespread and has bridged over a slope, it may be unstable and prone to failure. Also, look for signs of wind loading or new snowfall that could trigger a new slide. Assess the steepness and angle of the slope to determine if it’s prone to avalanching.
Safe Return Protocols
If you decide to return to the same area, follow safe protocols to minimize the risk of a secondary slide. Travel one at a time, use a rope to control the group, and stay on the edge of the debris. Avoid traveling in areas with recent avalanche activity or unstable snowpack. If you’re unsure about the safety of the terrain, consider finding an alternative route or delaying your descent.
