Kernpunkte

Low doesn't mean no avalanches. Watch for isolated wind slabs in the high alpine and thin to thick snowpack areas where triggering the deep persistent slab is more likely.

    This is combination of our midseason persistent weak layers and the weak facets & depth hoar that live at the bottom of the snowpack. The likelihood of triggering this layer has been decreasing but if triggered, would likely result in a large destructive avalanche.

Avalanche Summary

No recent observation of been noted.

Snowpack Summary

In sheltered northerly slopes above 2500m, 5-20 cm of soft snow exists. Isolated wind slabs exist at all aspects in the alpine.

The upper snowpack at treeline and below is a series of crusts. The lower snowpack is dry, faceted, and weak.

High north aspects offer the best spring riding conditions, though the snowpack remains susceptible to triggering deeper, unstable layers.
