Snow surface conditions are just about everything you can imagine, with some settled powder on sheltered shady slopes.
There were no avalanches reported from the backcountry yesterday but recent strong winds and a little new snow a few days ago produced several human triggered slides earlier this week.† These avalanches occurred mostly on north through east aspects above 8,500í.† The winds were strong enough to drift slopes well below the ridgelines and cross load the sides of gullies and sub-ridges.† On Sunday a group of skiers triggered a wind slab on the side of a cross-loaded gulley in Cardiff Fork.† The slide broke on a northwest facing slope at about 9,800í.† On Monday a skier in Mineral Fork triggered a slide (photo1, photo2) on an east facing slope at about 8,700í.†
have picked up again from the west and northwest.† Although widespread wind and sun crusts will
limit how much snow can blow around, be alert for fresh drifts.† If we get a few inches of new snow this
afternoon, expect shallow but sensitive drifts to develop quickly on the many
crusted slopes.† The crusts will allow
any triggered slides to move quickly and run far.† Under the varied surface snow are plenty of
weak layers that complicate the stability picture.† These deeper weak layers mean that in some
places avalanches in the newer snow may break down into deeper layers.† The stability in the
In areas sheltered from the sun and wind, the loose snow is sluffing easily on slopes up around 40 degrees steepness.
The danger of human triggered avalanches is MODERATE on slopes steeper than about 35 degrees with recent deposits of wind drifted snow.† Human triggered avalanches are possible in these areas.† There remains a distinct possibility that any new avalanche may step down into older snow.† Suspect areas for this would be upper elevation steep rocky chutes, areas that have slid earlier in the year and in areas that have a thinner snowpack.†
