Snowpack Summary

5cm of snow fell in the Coquihalla a few nights ago and has buried a thick layer of surface hoar on most sheltered and shady slopes. 2cm of snow fell on saturday night burying the same layer in the Duffey Lake area. This surface hoar may be sitting on a crust in sun and wind exposed areas making it especially touchy as soon as a sufficiently deep and cohesive slab forms. The thick rain crust from last weekend extends up to 1800m and is buried by 10-15cm of faceted snow. Snow pack depths and surface condition are highly variable in wind-exposed areas. Surface hoar buried 70 cms below the surface has gained strength, and just off the ground facets have been doing the same.
