Snowpack Summary
Alpine is either stripped of snow completely or offers a variety of wind affected surfaces. Surface faceting continues with cooler temperatures. Strong mid-pack overlies generally supportive basal layers. Decomposing surface hoar is found down 40cm to 80cm in isolated sheltered locations, in the very southern parts of the park.

Avalanche Problems
Persistent Slabs
Keep an eye out for sporadic weak layers within the snowpack. These layers may be present in a form of buried surface hoar, facet interfaces, thin to fat areas and/or sun crust.
- Dig down to find and test weak layers before committing to a line.
- Be aware of thin areas that may propogate to deeper instabilites.
Aspects: All aspects.
