Which of the following is a factor to consider when planning to recreate in avalanche terrain?

• A. Weather
• B. Elevation Gain
• C. Slope Angle
• D. Distance to Road

Answer: (A)

Weather drives snowpack stability and avalanche risk. When planning to recreate in avalanche terrain, you must consider forecasts and current conditions because snowfall, wind, and temperature changes shape the stability of the snow and the likelihood of slides. Fresh snow adds weight and can overburden weak layers, wind builds wind slabs on leeward slopes, and warming temperatures can weaken bonds within the snowpack. These weather-driven changes affect not only where and when avalanches might occur but also visibility and terrain choices for safer travel. While factors like elevation gain and slope angle matter for effort and route design, weather is the dynamic factor that most directly determines whether a slope is dangerous on a given day.
