Snowpack Summary
Cool temperatures through the day on Saturday created a crust on a previously moist or wet surface. Since then 25-40cm of fresh new snow has fallen to bury this crust. Looking down into the snowpack there are a few prominent melt-freeze crusts that were buried mid-December and are now 50 to 100cm below the surface. After heavy rain last Friday penetrated most of the snowpack, these crust layers have been reported to be bonding to the snow above and below. The rain last week has reduced the snowpack depth at 1000m to about 140cm and many early season hazards are still present at
