Avalanche Summary

Continued sluffing in steep terrain to size 1.0, otherwise no new.

Snowpack Summary

Up to 5cm of low density new snow overlies the January 4th interface. Moderate south/southwest winds have redistributed this new snow into small windslabs in immediate lee features in the alpine and exposed treeline.The January 4th interface consists predominantly of loose facets up to 30cm deep. In isolated locations (sheltered treeline and below treeline) surface hoar up to 12mm is present. There is a 1-3cm sun crust on steep south and west facing terrain. In exposed locations, old windslabs linger.The midpack is well bonded and strong. Concern remains in specific locations (Rossland Range) for the November 28 surface hoar buried 95cm.  The deep crust/facet combo from early November still exists and concern remains (although unlikely) for triggering from a shallow spot.
