Avalanche Summary

No new reports of avalanches since Friday when natural and remote triggered wind slabs size 1.5-2 were observed on north aspects in the alpine. Wind slabs appeared to be less sensitive by Saturday according to this well-travelled group's MIN report.

Snowpack Summary

Alpine surfaces are predominantly wind affected, but soft snow can still found in wind-sheltered terrain. A spotty layer of surface hoar may sit below recent snow, around 20 to 30 cm deep.

Below 1500 m, a thick melt-freeze crust is buried 50 - 100 cm deep.
