Avalanche Summary
Nothing new.
Snowpack Summary
Surface faceting continues. Sun crust on steep solar aspects. Recent winds have created thin wind slabs in cross-loaded and reverse wind-loaded features at Treeline and above in the past 48hrs. The Feb 10th persistent weak layer continues to produce shears down 30 to 70cm. The midpack remains supportive near the divide, but is significantly weaker to the east side of the range and at lower elevations.
Problems
Persistent Slabs
The Feb 10 persistent weak layer is highly variable in nature (a mix of facets, sun crust, wind slab, surface hoar) and is still producing shears down 30 to 60cm in the snowpack. Isolated whumpfing and cracking continues to occur on this layer.
Choose well supported terrain without convexities.>Avoid cross loaded slopes at or above treeline.>
