Even though the likelihood of triggering a slide is decreasing, the potential size of avalanches is not. Obvious signs of instability like cracking and collapsing have almost disappeared, but you can still trigger a large avalanche. You will most likely 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. Multiple people can ride a slope before it slides. About forty percent of avalanche fatalities occur at MODERATE (2 of 5) danger, so don't let your guard down. You can find safer riding on low-elevation wind-sheltered slopes and lower-angle slopes.
