The Avy Rose shows the forecasted danger by elevation and aspect.

It adds more detail about where you are likely to find the dangers mentioned in the forecast. The inner circle shows upper elevations (mountain top), the second circle is middle elevations, and the outer circle represents lower elevations.

Think of the Rose as a birds-eye view of a mountain, looking down from above. The rose allows our forecasters to visually show you which parts of the mountain they are most concerned about.

Avalanche Activity

Over the last two-three weeks, we've had reports of isolated surface wind slab avalanches (D1-D2), both natural and human-triggered, in top-loaded and cross-loaded terrain between 2500-5000ft. Some wind slabs were sliding on low-angle slopes as low as 25 degrees, and appeared to be sliding on a buried surface hoar layer 10-30cm deep. Distribution of these avalanches was limited to wind loaded areas that had been protected from strong N/NW winds.

Weather

We've had 6 weeks of cold and mostly dry weather. The drought continues, but no worries because ski conditions have been great. Our last snowfall was 4-5" that fell about a week ago and freshened up the slopes. More clear and chilly weather is in store for this weekend, with continuing moderate NW winds. A strong but fast-moving front will bring snow Sunday night, probably 3-8".

Additional Information

If you get out riding, please send in an observation!

Do a rescue practice with your partners. Always carry a beacon, shovel, and probe, and KNOW HOW TO USE THEM.

Practice good risk management, which means only expose one person at a time to slopes 30 degrees and steeper, make group communication and unanimous decision making a priority, and choose your terrain wisely: eliminating unnecessary exposure and planning out your safe zones and escape routes.
