If you find a shallow spot on a steep slope, you can trigger an avalanche that breaks on weak layers in the top meter of the snowpack. The most likely slopes to find a shallow trigger point are where there was very little snow before the big upslope storm from a week ago. Assess the slopes you plan to travel and identify and avoid shallow trigger points.
