You can easily trigger a large avalanche where recently wind-deposited snow rests on top of fragile weak layers near the ground. Wind-drifted slopes with a visibly deeper snowpack will break near the ground and can run far. You can trigger an avalanche from a long distance away, even low on a slope with steep terrain above. You can find safer options on southerly-facing terrain or choose slopes less than about 30 degrees without steep terrain overhead.
