Snowpack Summary

Northerly winds at all elevations continue to redistribute the new snow from earlier this week. This new snow has buried various pre-existing crusts, surface hoar, old wind-affected surfaces, or facets.

The mid and lower snowpack is generally well settled with a series of crusts and facetted snow.

The height of snow at treeline is roughly 50 to 150 cm.
