Lo esencial

Warm temperatures and constant weather are helping to stabilize the snowpack, but it will take more time to bridge and strengthen the snowpack over the weak basal layers near the ground.

Snowpack Summary

The Feb 13th rain crust lies underneath a melt-freeze crust up to 2000m elevation. The melt-freeze crust goes up to 2200m.  A mixture of rounded and facetted layers are sandwiched between these upper layers and the weak depth hoar/ facets prevalent in the lower snowpack down to ground.
