You can trigger avalanches on weak layers buried about three feet deep. It is getting harder to trigger avalanches on this layer, but if you find a weak spot, you could trigger a large dangerous avalanche. Shallow slopes with many trigger points will be the most hazardous slopes. Multiple people could ride a slope before it is triggered and you may get no feedback like cracking or collapsing. If you travel on slopes with a weak layer lower-angle planar slopes without trigger points will reduce your hazard or just avoid slopes with a weak layer altogether.
