This is another example of an avalanche that pulled out mid way down the slope. The UAC forecasters speculate the reason is that there is more wind crusts and slabs that are giving the upper starting zones a little more strength over the persistent weak layers. Our storm from mid January wasn't enough to overload many of these starting zones. Farther down the slopes where the previous crusts and slabs were not present, it didn't take as much weight to make them fail. This means that the upper starting zones that didn't avalanche are still holding the buried persistent weak layers.
Nice pile of debris spitting out of the gully.
