Quick Answer
Identify potential avalanche terrain by looking for steep slopes, recent snowfall, and signs of instability such as recent avalanches, cracking snow, or whumping sounds. Use your clinometer to measure slope angles over 30 degrees and terrain traps such as gullies or ridges to increase awareness.
Assessing Slope Angles
When navigating terrain, use a clinometer to measure the slope angle. This is crucial for identifying potential avalanche terrain. Set the clinometer to the slope and read the angle displayed. Angles over 30 degrees indicate steeper terrain that may be more prone to avalanches. Be cautious of slopes between 30-40 degrees, as these are often the most unstable. If the clinometer displays an angle over 40 degrees, consider this a red flag for potential avalanche terrain.
Identifying Terrain Traps
Look for terrain traps such as gullies, ridges, and cliffs. These features can funnel flowing snow and increase the likelihood of an avalanche. Measure the slope angle of these features using your clinometer and assess their potential for trapping snow and triggering an avalanche. Avoid terrain traps with steep angles and recent snowfall.
Recognizing Signs of Instability
Be aware of signs of instability in the terrain, such as recent avalanches, cracking snow, or whumping sounds. These indicate that the snowpack is unstable and may be prone to avalanches. If you witness any of these signs, reassess the terrain and consider alternative routes. Remember that recent snowfall can make the terrain more unstable, so be cautious of new snow cover and assess the risk accordingly.
