You can trigger a small avalanche that breaks in the upper snowpack on northerly and easterly-facing slopes at any elevation. An avalanche in motion will gouge into a thick layer of buried weak snow in the top two feet of the snowpack. In wind-drifted terrain features an avalanche might break as a slab initially before entraining loose, granular snow in the upper snowpack. In wind-sheltered terrain, one will run as a loose avalanche and gain mass as it moves downslope. You are unlikely to trigger an avalanche on any slopes less than 35 degrees.
