Assessing terrain challenges during wilderness evacuations — which to avoid?

Avoiding Steep Slopes

Steep slopes can be particularly hazardous during evacuations, especially when carrying heavy or bulky equipment. Aim to avoid slopes with angles exceeding 30 degrees, as these can lead to loss of balance and increased risk of falls. When traversing a steep slope, use a rope or a makeshift handrail to provide additional stability, and consider anchoring yourself to a fixed object to prevent sliding. If the slope is too steep or unstable, consider detouring to a safer route.

Navigating Unstable Terrain

Loose or slippery terrain can be treacherous, particularly in areas with recent rainfall or snowmelt. When encountering loose terrain, such as scree or talus, try to distribute your weight evenly to minimize the risk of dislodging rocks. Avoid making sudden movements, and use trekking poles or a walking staff to provide additional stability. If the terrain is extremely slippery, consider using crampons or traction devices to improve your footing.

Managing Water Hazards

Areas with standing water can be particularly hazardous, especially during evacuations. When encountering standing water, avoid wading through it, as this can lead to waterborne illnesses or hypothermia. Instead, try to find a safe crossing point, such as a shallow area or a natural ford. If you must wade through water, wear protective gear, such as waders or waterproof boots, and avoid getting your equipment wet.
