Obvious signs of instability like cracking and collapsing have almost disappeared, but you can trigger a large avalanche. The size of avalanche will not change with the drop in danger. You are most likely to trigger an avalanche at the edge of wind-loaded slopes and in shallow rocky areas. Don't assume tracks on a slope mean it is safe, just that the rider was lucky enough not to find a trigger point. 40% of avalanche fatalities occur at MODERATE, so don't let your guard down. You can find safer riding on low-elevation wind-sheltered slopes and lower-angle slopes.
