You can trigger an avalanche where a thick slab rests on top of weak snow on slopes with less than three or four feet of snow depth. The more dangerous slopes are near and below treeline and in wind-sheltered areas where the slabs are thinner. In areas with a deeper snowpack, you may trigger a slide if you find a thin spot in the slab. Those are often near rock outcrops, small trees, or near the sides of a slope. Do your best to avoid these shallow areas or stick to low-angled slopes.
