You may be able to trigger small avalanches in recently wind-drifted snow on steep slopes above treeline. North and easterly-facing slopes below ridgelines and in cross-loaded terrain features harbor the deepest drifts. Cracking in the snow surface is an indication of an unstable slope. Avalanches will likely be small but can be dangerous if triggered above rocks and cliffs. Slopes protected from the wind offer safer and more enjoyable backcountry travel.
Your chances of triggering small loose avalanches increase as the snowpack deteriorates. To avoid this issue, steer clear of steep near and below treeline slopes that are fully cohesionless.
