You can trigger an avalanche where snow from the past few weeks combined with primarily westerly wind created cohesive slabs of snow on top of weak, cohesionless snow. Identify and avoid wind-loaded terrain to reduce your chances of triggering an avalanche. You can identify wind-loaded slopes by there smooth, rounded, often wave-like snow surface appearance and the hollow, hard feeling if you are traveling on them.
