You can trigger an avalanche where you find a cohesive slab of snow on top of weak, cohesionless snow generally on northwest through north to southeast-facing slopes. The most dangerous slopes are where recent wind drifted additional snow onto the leeward sides of ridgelines. Safer travel options exist by sticking to low-angle slopes when traveling on aspects of concern without steep slopes above you, as you might be able to trigger an avalanche from a distance.
