Avalanche Summary
Triggering an avalanche that breaks in old snow is becoming less likely. If you were to trigger one, it would be on steeper slopes at upper elevations. You are more likely to impact a weak layer and trigger an avalanche near exposed rocks and on steep convex rolls where a buried layer of firm snow sits above older, weaker snow.
Recent wind-drifting may increase sensitivity of surface snow, but will not be enough to increase avalanche danger. For safer riding options, stick to slopes less than 35 degrees in steepness.
