A tale of two snowpack structures. The left image and an excellent ob from Bill and Andy in Upper Humpy Basin represents a deep pack that's gaining strength and it would be difficulty to trigger a slide. The right image and an equally excellent ob from Ted on the east side of the range in Boundary Creek illustrates a thinner pack and the type of setup where we could still trigger a slide that breaks to old snow.
The Valentines storm is settling and gaining strength, as a matter of fact, getting around is seamless because the snow will feel solid under our skis, board, or sled... and that's good news. But it's a double edge sword and we need to think not only about the snow we're riding in, but also the snow we're riding on. And we need to remember most of our winter snowpack is resting on an early season persistent weak layer (PWL) or weak, sugary facets about a foot above the ground.... think strong snow on weak snow. The PWL exists on most slopes except those facing due south and southwest.
Avalanche conditions remain deceptively tricky and here's why-
The probability of triggering a deep dangerous avalanche is generally low, but the consequences are high because the entire seasons snowpack will crash down on top of you if you have misjudged the snowpacks stability. Now, you wouldn't go to Vegas and bet against the house with those odds right? Personally, I don't entirely trust anything in the snowpack I can't manage, so I'm going to continue avoiding terrain that harbors questionable snowpack structure. Of course the usual suspects come to mind... steep, rocky, upper elevation slopes facing the north half of the compass is bulls-eye terrain and should be considered suspect. With all the great coverage across the range and so many other riding options, there's no reason to roll the dice or pull on the dogs tail.
What to do? Unfortunately it's just a season with a dangerous snowpack. There's no way around that fact, and the key to longevity is avoiding big, open terrain, especially those in the Alpine that are steeper than about 30 degrees.
With such a supportable slab on top of the PWL, a slope may have many sets of tracks on it and still slide if someone hits a thin spot in the snowpack near a rock or bush hidden under the snow, like in the image above.
