Points saillants

Decent skiing can be found in sheltered locations.  Due to the variability in the snowpack, we are still treating larger alpine features with caution.  SH

    Watch for thin snowpack areas in steeper terrain where triggering the basal depth hoar/crust is possible.

Weather Forecast

Light to mod. N winds in the alpine for Saturday with lows around -25C and highs in the -15C range.  No snow in the forecast except for a trace on Sunday.

Snowpack Summary

5-15cm of snow has buried the Jan 30th surface hoar / sun crust layer. This new snow came in with very little wind, but there have been some soft storm slabs building in the immediate lees of S through SE ridgetops.  The basal facets remain weak, but the overall snowpack is gaining strength.

Avalanche Summary

No new avalanches observed in the past several days.
