Avalanche Summary
Recent winds drifted a small amount of new snow into isolated slabs above treeline. Leeward ridgelines and cross-loaded terrain features on east and northeast-facing slopes are the most likely to harbor pockets of firm, drifted snow. If you were to trigger an avalanche in a patch of wind-drifted snow, it would be small.
