Quick Answer
Assess the slope angle and surrounding terrain to determine if your shelter is in an avalanche prone area. Look for signs of recent avalanches and understand local avalanche forecasts. Consider the aspect, elevation, and vegetation when evaluating the risk.
Assessing Slope Angle and Terrain
When assessing the slope angle and surrounding terrain, look for signs of instability. A slope with an angle of 30-40 degrees is generally considered stable, while slopes between 40-45 degrees are susceptible to small avalanches. Slopes above 45 degrees are at high risk for large and destructive avalanches.
Local Avalanche Forecasts and History
Understand local avalanche forecasts and recent avalanche activity in the area. Check with local mountaineering guides, park rangers, or avalanche centers for information on current conditions. If there have been recent avalanches in the area, it’s best to choose a different location for your shelter.
Aspect, Elevation, and Vegetation
Consider the aspect, elevation, and vegetation when evaluating the risk. North-facing slopes are generally more stable than south-facing slopes, which are exposed to direct sunlight and warmer temperatures. Avoid areas with vegetation that has been recently disturbed or is sparse, as these can be signs of unstable terrain. Avoid areas with avalanche chutes or gullies, as these are high-risk areas for avalanches.
