Avalanche Summary
No new avalanches have been reported recently but observations have been limited.
Continue to support your backcountry community and please consider submitting a MIN report.
Snowpack Summary
Up to 15cm of low density new snow exists in non-wind effected terrain. This new snow has likely formed new wind slabs in high alpine terrain and buried a variety of surfaces including old wind slab, facets and even bare ground.
In the mid pack it could be possible to find a thin layer of facets between old wind slabs. This layer recently produced sudden results in snowpack tests.
The height of the snowpack is variable. In areas lee of the prevailing wind, depths of up to 170cm can be found. At the lower elevation treeline terrain, snow depths decrease and are estimated at 60-90 cm.

Terrain and Travel Advice
- Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
- Closely monitor how the new snow is bonding to the old surface.
Problems
Wind Slabs
Wind slabs could be found on all aspects in the alpine. These slabs could be more reactive where they overlie facets. There is lots of unconsolidated snow availible for transport, if the winds pick up new wind slabs will form.
