The most dangerous slopes are where winds drift new snow below ridgelines and close to terrain features, overloading weak layers deeper in the snowpack. On these aspects, the avalanche you trigger in the surface snow will likely step down to weaker layers deeper in the snowpack. It is possible to trigger an avalanche from below and at a distance. Don't assume tracks on a steep slope mean it is safe. You can find safer travel on lower-angle slopes.
