Kernpunkte

It's possible to trigger a slab 2-3 feet deep in very steep or wind loaded terrain. Weak layers up to three feet from the surface can collapse and fail without warning signs.  Strong winds may build fresh wind slabs. Continue to be cautious in the terrain and avoid riding on steep slopes over terrain traps, even though you will see many other tracks.

    Weak snow from January lies 2-3 feet below  the snow's surface. Though this drought layer has gained strength with time, triggering a large and widely propagating avalanche remains possible, especially in very steep terrain above about 8,000'. This problem continues to deserve respect, especially in high consequence terrain and places where the slab may be thin enough for the weight of a person or sled to hit the weak layer. You can find this layer by digging or probing or, alternatively, just avoid slopes over 30 degrees, especially over nasty terrain.

    Cornice Fall: Large triggers such as a falling cornice could trigger a larger avalanche. While unlikely, it's a good idea to give cornices some space.

    Recent avalanche near Split Rock. This avalanche was on the smaller side, but if piled up in a creek of depression (terrain trap), it could have still buried a rider.

    Snow which fell over the past several days drifted and formed slabs. These should be difficult trigger due to the thin ice crust capping the snow.   You are most likely to find these slabs above 9,000', near ridgetops and around cliffs.  Wind speeds today could approach 50 mph which may rip up ice crusts and access loose snow beneath. Two or three inches of new snow could fall this morning and add more snow to build slabs.

    3/7 rain crust up to 10,200' on all aspects.

Avalanche Discussion

Recent warm emperatures, some sunshine and a freezing rain and icing event have resulted in a mixed bag of surfaces. You'll find lots of refrozen snow and crusts around on solar slopes and to mid-elevation northerlies as well.  A lot of uncertainty exists in the forecast due to unknowns regarding the distribution and durability of ice lens and rime crusts on the surface. Rain showers 36-48 hours and some clearing skies and warm temperatures yesterday have no doubt made snow on the ground harder to move but the degree to which that is true remains uncertain. 

Thanks for submitting your observations. Observations like the one from Prater last night can save lives!
