Confidence
Moderate
Avalanche Summary
Loose dry avalanches up to size 2 in very steep rocky alpine terrain were noted over the past few days. Some are scrubbing to ground. They do not appear to be initiating any deeper weakness' in the snowpack.
Snowpack Summary
About 10cm of snow fell in the north and east section of the park with about 3cm around the Parker Ridge area. Tree line snowpack depth is an average of 45-75cm. The snowpack is weak and largely unsupportive after this cold weather.

Terrain and Travel Advice
- Loose avalanches may start small but they can grow and push you into dangerous terrain.
Avalanche Problems
Loose Dry
A handful of loose dry avalanches have occurred recently with one scrubbing to ground. They are currently limited to specific terrain such as very steep alpine rocky terrain yet enough of a concern if a person is standing below it or gets swept away. This currently is our most active problem.
Aspects: All aspects.
Elevations: Alpine.
Likelihood: Very Likely
Expected Size: 1 - 2
Deep Persistent Slabs
You must keep this basal layer on your radar as triggering is possible in isolated features, such as steep rocky terrain where you find yourself standing on the surface and not wallowing in facets, that's the problem slab.
Aspects: All aspects.
Elevations: Alpine.
Likelihood: Possible
Expected Size: 1 - 2.5
