Avalanche Summary
There were no new avalanches observed on Tuesday.
On Monday, naturally triggered size 1 storm slabs were observed, and loose dry sluffing in steep and sheltered terrain features.
Backcountry reports are very limited. If you head out, please post any photos or observations to the Mountain Information Network.
Snowpack Summary
Snow continues to accumulate, with many areas seeing 90 to over 130 cm of recent snow over a melt-freeze crust, with deeper deposits in wind-loaded terrain at treeline and above.
Early-season hazards remain a concern concealed beneath the new snow and will continue to be until the snowpack settles and becomes more supportive.
