Degrees of Avalanche Danger ?
Avalanche Problem #1: Storm Slab
Above 1500ft we have a meter+ of new snow settling from this last week. Human triggered avalanches are still likely within the new snow, especially on wind loaded north aspects. Any slopes steeper than 30 degrees should be treated with caution right now. You can minimize the danger of storm slabs by traveling in low angle terrain, sticking to the trees, and avoiding wind affected slopes. Give the new snow some time to bond and compress.
Recent Avalanche Activity
There were isolated areas of wet and dry loose slides coming down from steep/cliffy terrain, mainly on sun-affected slopes. None of this activity was large, and occurred during warm temperatures earlier this week.
Snow totals from the 12th-17th are around 48-70″ above 1200ft (highest amounts in the Lutak zone, with less towards the Pass). Below that level was mostly rain. South winds were strong throughout, and there were brief periods of rain up to 2500ft near town.
Tuesday will bring a much needed break in the weather with cooler temperatures and light north winds. More snow is expected Wednesday-Thursday with cold temperatures and accumulations at sea level. Currently it looks like 4-8″ of new snow, possibly more if snow continues Thursday. Winds will generally remain northerly.

2017 New Year’s resolution – develop backcountry habits to LIVE TO RIDE ANOTHER DAY:
- everyone in my riding group has a functioning beacon, probe, and shovel (& floatpack)
- my group chooses to avoid slopes with rocky trigger points
- my group chooses to avoid slopes with terrain traps; cliffs, gullies, and creek ravines
- my group agrees that one rider on a steep slope at a time is what we do
- my group gathers out of harm’s way, beyond the run-out
- my group reviews our day – where could we have triggered a slide? how can we improve our plan?
