Strong winds are drifting snow on easterly-facing slopes. Here you are most likely to trigger an avalanche where cohesive slabs of stiff snow lay over buried weak layers. The avalanche you trigger in the surface snow could be large enough to bury you but could break deeper into weak layers buried two to three feet down. Multiple sets of tracks on a slope do not mean it is safe. Parties have reported the second, third, and even fourth person has triggered a slide. Shallow terrain with many trigger points are the slopes where you are most likely to trigger a deeper avalanche. You can find safer riding on slopes sheltered from the wind without a slab or on lower-angle slopes.
