Snowpack Summary
Up to 8 cm of new snow over the last 48 hours at treeline.
The wind effect exists in the high alpine, but many sheltered areas have soft snow. The mid-pack is generally strong; however, a facet layer can be found near the ground in shallow snowpack areas. At treeline, average snowpack depth ranges from 110 to 160 cm.
