Which factors can you control within the AVI triangle?

• A. Snowpack, People, Weather, Terrain
• B. Snowpack and Weather
• C. Wind and Moisture
• D. Temperature and Humidity

Answer: (A)

The AVI triangle is about the elements you can actively influence when planning and moving in avalanche terrain. The factors you can control are Snowpack, People, Weather, and Terrain. You influence Snowpack by choosing slopes with stable snow conditions and by timing your trip to avoid weak layers. You influence People through group decisions, communication, and behavior, which directly affect how risks are managed. You influence Weather by selecting travel windows with favorable forecasts and by adjusting pace and preparedness in response to conditions. You influence Terrain by picking routes and slope characteristics that reduce exposure to avalanche-prone areas. Because these four aspects are what you can actively shape through planning and actions, they form the controllable set in the AVI triangle. The other options omit or misrepresent these controllable elements, whereas this choice captures the full range of factors you can influence.
