Snow Characteristics Comments

The north end of the Skyline got a nice shot of snow Saturday night.  It was a bit higher density than Friday's new snow.  This coupled with the wind made the snow feel slightly "upside down".  Lots of wind damage along the higher elevations.  The mid elevations also got stirred up and you'll find scalloped and wind crusted surfaces in the open areas.

Obvious wind loading occurring during the day. We observed a number of natural cornice falls that released some small slabs below them.

Problem #1 Comments

Upper elevation more east facing steep slopes should be avoided until the newly drifted snow has some time to adjust and stablize.  The drifts seemed stubborn so you might not see any signs of instability until you get onto one of these drifts only to have it crack out.  It looks like the wind will shift more to the southwest on Monday and it looks like it will be a bit gusty as the next storm approaches.

Comments

Below is photo of a cornice that broke off naturally during the wind loading.  This is the type of slope you'll want to avoid again on Monday.

Most terrain has a MODERATE avalanche danger but there are areas with a CONSIDERABLE avalanche danger on the higher more east facing steep slopes.
